What happens to light when it passes from air into water?
The refractive index of glass is 1.5. What does this mean?
What is the critical angle for total internal reflection?
A swimming pool appears shallower than it actually is. This is due to:
Sample Questions
Which of the following factors affect the refractive index of a medium?
Show answer
Density of the medium, Temperature of the medium, Wavelength of light
Refractive index depends on density, temperature, and wavelength. It does not depend on intensity of light.
Which conditions are necessary for total internal reflection?
Show answer
Light travels from denser to rarer medium, Angle of incidence > critical angle
For TIR, light must travel from denser to rarer medium and angle of incidence must be greater than critical angle.
The first law of refraction states that:
Show answer
Incident ray, refracted ray and normal lie in same plane
The first law states that incident ray, refracted ray and normal at point of incidence lie in the same plane.
When light passes through a glass prism, the emergent ray:
Show answer
Deviates towards the base
When light passes through a prism, it deviates towards the base due to refraction at both surfaces.
