How is the reflection of light ray from a plane mirror different from the refraction of light ray as it enters a block of glass?
A monochromatic ray of light passes from air to glass. The wavelength of light in air is λ, the speed of light in air is c and in glass is V. If the absolute refractive index of glass is 1.5, write down
- the relationship between c and V,
- the wavelength of light in glass.
How does the speed of light change when it passes from glass to water?
Fill in the blanks to complete the following sentence
The refractive index of glass with respect to air is 3/2. The refractive index of air with respect to glass will be ……………….
Draw a ray diagram showing the lateral displacement of a ray of light when it passes through a parallel sided glass slab.
A ray of light strikes the surface at a rectangular glass slab such that the angle of incidence is 45o.
In each case, draw diagram to show the path taken by the ray as it passes through the glass slab and emerges from it.
Name the phenomenon responsible in the following case:
Apparent bending of a stick in water
A ray of light passes from water to air. How does the speed of light change?
Write a relation between the angle of incidence (i), angle of emergence (e), angle of the prism (A), and angle of deviation (d) for a ray of light passing through an equilateral prism.
