What is meant by ‘refraction of light’?
- With the help of a diagram, show how when light falls obliquely on the side of a rectangular glass slab, the emergent ray is parallel to the incident ray.
- Show the lateral displacement of the ray on the diagram.
A ray of light when passes from glass to air, bends towards the normal.
The depth of a pond when seen from above appears to be less.
Water is optically .......... than air.
Numerical problems.
The speed of light in water is 2.25 × 108 ms–1. If the speed of light in vacuum is 3 × 108 ms–1, calculate the refractive index of water.
Assertion and reasoning type
- Assertion: If the refractive index of the medium is high (denser medium) the velocity of the light in that medium will be small
- Reason: Refractive index of the medium is inversely proportional to the velocity of the light
Which object use the reflection of light?
Under what circumstances there won’t be any refraction of light when it enters from one medium to another?
