Class 12th Ray Optics and Wave Optics MCQs

Here are the study notes on Ray Optics and Wave Optics for Class 12th, along with 100 MCQs:

• Study Notes:*

Ray Optics

• Refraction of light occurs when light passes from one medium to another with a different optical density
• Snell's Law: sin(i) / sin(r) = μ1 / μ2, where i is the angle of incidence, r is the angle of refraction, μ1 is the refractive index of the first medium, and μ2 is the refractive index of the second medium
• Total Internal Reflection occurs when light passes from a denser medium to a rarer medium and the angle of incidence is greater than the critical angle
• Mirrors: Plane mirrors, Spherical mirrors (concave and convex), Mirror formula: 1/f = 1/do + 1/di
• Lens: Convex lens, Concave lens, Lens maker's formula: 1/f = (μ-1)(1/R1 - 1/R2)
• Refraction through a prism: Angle of deviation, Dispersion of light

Wave Optics

• Wave theory of light: Light is a transverse wave, Electromagnetic wave
• Interference of light: Superposition of light waves, Constructive and destructive interference
• Young's Double Slit Experiment: Interference pattern, Fringe width, Fringe spacing
• Diffraction of light: Bending of light around an obstacle, Diffraction grating
• Polarization of light: Plane polarized light, Brewster's Law
