Question

State two effects caused by the refraction of light ??​

Answer 1

Following are the effects of refraction of light in our daily life.

1.A swimming pool always looks shallower than it really is, because the light coming from the bottom of the pool bends when it comes out at the surface due to refraction of light.

2.A straight stick which is immersed partly in water always looks to be bent at the surface of water, because the light coming from the stick bends when it comes out at the surface due to refraction of light.

3.A coin or stone lying at the bottom of a container filled with water appears to be raised because of refraction of light.

4.A line or a spot of ink on a paper always appears to be raised when viewed through the glass slab due to the refraction of light.

5.Twinkling of stars is due to the refraction of light.

6.Optical illusions such as mirage and looming are also produced due to refraction of light.
