Study reflection, refraction, lenses, mirrors, optical instruments and vision defects.
Ray Optics is the branch of Physics that explains the behaviour of light using the ray model. It deals with reflection, refraction, mirrors, lenses, optical instruments and defects of vision.
This chapter is extremely important for CBSE Class 12, NEET, JEE Main, JEE Advanced, IB Physics, IGCSE Physics and A-Level Physics.
Students learn how images are formed by mirrors and lenses, how light bends while travelling from one medium to another and how optical instruments help us observe objects more clearly.
The ray approximation is valid when the wavelength of light is much smaller than the size of the obstacle or aperture.
In Ray Optics:
Complete chapter overview for reflection, refraction, mirrors, lenses and optical instruments.
Study laws of reflection, regular reflection, diffuse reflection and image formation basics.
Image formation, lateral inversion, multiple images and rotation of mirror.
Concave mirror, convex mirror, ray diagrams and image characteristics.
Use mirror formula, sign convention and magnification for numerical problems.
Snell law, refractive index, apparent depth and bending of light.
Critical angle, conditions for TIR and important applications.
