+91-9958461445
If you live in Dubai Silicon Oasis and Physics has started becoming difficult, confusing, numerical-based, formula-heavy, or too abstract, then you are not alone. Many students attend school regularly, complete homework, read notes, and still feel that Physics is not becoming clear. The reason is simple: Physics is not a subject of memorising formulas only. Physics needs concept clarity, diagram understanding, mathematical confidence, and regular numerical practice.
This is where Kumar Sir from Kumar Physics Classes helps students in a very systematic way. If a student in Dubai Silicon Oasis is preparing for CBSE Physics, ICSE Physics, IGCSE Physics, IB Physics, A-Level Physics, AP Physics, NEET Physics or IIT JEE Physics, then the focus should be on understanding the concept first and then applying it in questions.

Why Students in Dubai Silicon Oasis Need A Good Physics Tutor
Dubai Silicon Oasis is a well-developed residential and educational area. Many students living here study in good schools and follow different curriculums such as CBSE, British curriculum, IB, American curriculum and Indian competitive exam preparation. But even good school teaching is sometimes not enough because every student has a different learning speed.
Some students understand theory but get stuck in numericals. Some students can solve easy questions but fail in application-based questions. Some students know formulas but do not know where to apply them. Some students become weak because their basic concepts from lower classes are not strong.
A good Physics Tutor in Dubai Silicon Oasis should not only teach chapters but should also build the student’s thinking process. Kumar Sir focuses on concept clarity, step-by-step derivation, diagram-based explanation, formula application, numerical practice and exam-oriented preparation.

Physics Tutor in Dubai Silicon Oasis for IGCSE, IB and A-Level
Students following international curriculum need a different style of preparation. IGCSE Physics, IB Physics and A-Level Physics require conceptual clarity, practical understanding, graph interpretation and structured answer writing.
Kumar Sir helps students understand the topic deeply and also teaches how to write answers according to the exam pattern. Whether it is electricity, waves, forces, energy, thermal physics, atomic physics or fields, every topic is explained with diagrams and examples.
Common Problems Students Face in Physics
Many students say:
“I understand in class but cannot solve questions.”
“I know the formula but do not know where to apply it.”
“I forget concepts during exams.”
“I make calculation mistakes.”
“I cannot understand derivations.”
“I get confused in graphs and diagrams.”
These problems are common. The solution is regular concept-based learning and guided practice. Kumar Sir focuses exactly on this.

Dispersion of Light: 40 Questions with Answers
1. What is dispersion of light?
Answer: Dispersion of light is the splitting of white light into its constituent colours when it passes through a prism.
2. Why does dispersion occur?
Answer: Dispersion occurs because different colours of light travel with different speeds in a medium and have different refractive indices.
3. Which colour deviates the most in a prism?
Answer: Violet deviates the most.
4. Which colour deviates the least in a prism?
Answer: Red deviates the least.
5. What is the order of colours in the spectrum?
Answer: VIBGYOR: Violet, Indigo, Blue, Green, Yellow, Orange, Red.
6. What is VIBGYOR?
Answer: VIBGYOR is the sequence of colours obtained when white light is dispersed.
7. Why does violet deviate more than red?
Answer: Violet has a higher refractive index and lower speed in glass than red light.
8. Why does red deviate least?
Answer: Red light has a lower refractive index and higher speed in glass.
9. What is angular dispersion?
Answer: Angular dispersion is the angular separation between two colours after dispersion by a prism.
10. What is dispersive power?
Answer: Dispersive power is the ability of a material to separate different colours of light.
11. What is the prism formula?
Answer: For a prism,
mu = sin[(A + Dm)/2] / sin(A/2)
where mu is refractive index, A is angle of prism, and Dm is minimum deviation.
12. What is angle of deviation?
Answer: Angle of deviation is the angle between the incident ray direction and emergent ray direction.
13. What is minimum deviation?
Answer: Minimum deviation is the least deviation produced by a prism for a particular colour.
14. What happens at minimum deviation?
Answer: At minimum deviation, angle of incidence equals angle of emergence.
15. At minimum deviation, what is the relation between r1 and r2?
Answer: r1 = r2 = A/2.
16. At minimum deviation, what is the relation between i and e?
Answer: i = e.
17. What is the relation between A, r1 and r2?
Answer: A = r1 + r2.
18. What is the relation between deviation, incidence, emergence and prism angle?
Answer: D = i + e – A.
19. Why does a prism produce spectrum but a glass slab does not?
Answer: In a glass slab, emergent rays are parallel to incident rays, so colours recombine. In a prism, different colours emerge in different directions.
20. What is pure spectrum?
Answer: A pure spectrum is a spectrum in which colours are sharply separated without overlapping.
21. What is impure spectrum?
Answer: An impure spectrum is a spectrum in which colours overlap each other.
22. What is dispersion without deviation?
Answer: Dispersion without deviation means white light splits into colours, but the mean ray emerges parallel to the incident ray.
23. How is dispersion without deviation produced?
Answer: It is produced by combining two prisms of different materials in opposite directions so that their deviations cancel but dispersion remains.
24. Which prisms are commonly used for dispersion without deviation?
Answer: Crown glass prism and flint glass prism.
25. Why are crown and flint glass used?
Answer: They have different dispersive powers and refractive indices, which help cancel deviation while keeping dispersion.
26. What is the condition for no net deviation?
Answer: Net deviation = 0, so deviation by first prism equals deviation by second prism in opposite direction.
27. What is the condition for dispersion without deviation?
Answer:
(mu1 – 1) A1 = (mu2 – 1) A2
for mean colour deviation cancellation, but dispersions are not equal.
28. What is deviation without dispersion?
Answer: Deviation without dispersion means white light bends, but it does not split into colours.
29. How is deviation without dispersion achieved?
Answer: By using two prisms of different materials placed oppositely so that dispersion cancels but deviation remains.
30. What is the condition for deviation without dispersion?
Answer:
omega1 (mu1 – 1) A1 = omega2 (mu2 – 1) A2
where omega is dispersive power.
31. What is a prism?
Answer: A prism is a transparent optical medium bounded by two plane refracting surfaces inclined at an angle.
32. What is angle of prism?
Answer: The angle between the two refracting surfaces of a prism is called angle of prism.
33. What is refracting edge?
Answer: The line of intersection of the two refracting surfaces of a prism is called refracting edge.
34. What is principal section of prism?
Answer: A section perpendicular to the refracting edge is called principal section.
35. Why is the spectrum continuous?
Answer: Because white light contains all wavelengths in the visible range.
36. Which colour has the longest wavelength?
Answer: Red has the longest wavelength.
37. Which colour has the shortest wavelength?
Answer: Violet has the shortest wavelength.
38. Which colour has maximum frequency?
Answer: Violet has maximum frequency.
39. Which colour has minimum frequency?
Answer: Red has minimum frequency.
40. What is the main cause of dispersion in a prism?
Answer: The refractive index of prism material depends on wavelength; this is the main cause of dispersion.
