Class 10 Science Chapter 9 Extra Questions
What do you know about the diffraction of light?
If an opaque object on the path of light becomes very small, light has a tendency to bend around it and not walk in a straight line – an effect known as the diffraction of light.
Why do we use Convex mirrors as rear-view mirrors?
Convex mirrors are normally used as rear-view mirrors in vehicles. These mirrors are preferred because they always give an erect image. They have a wider field of view as they are curved outwards. In this way, convex mirrors enable the driver to view much larger area than would be possible with a plane mirror.
What is Snell’s law of refraction?
During the refraction of light, the ratio of sine of angle of incidence to the sine of angle of refraction is a constant, for the light of a given colour and for the given pair of media. This law is also known as Snell’s law of refraction.
What is meant by Power of a Lens?
The ability of a lens to converge or diverge light rays depends on its focal length. The power of a lens is defined as the reciprocal of its focal length.
