Light Test - 44...

Two plane mirrors at an angle $({x}^{o})$ produces $5$ images of a point. The number of images produced when ${x}^{0}$ is decreased to ${(x-30)}^{o}$ is

Two plane mirrors are at $45^{o}$ to each other. If an object is placed between them then the number of images will be:

__________ energy gives us the sensation of vision.

Image formation takes place by:

If you read the words of your book, the reflection is

The image of an object is formed due to the _________ of light rays by the eye lens on the retina. 

Diffused reflection

Light passes through a prism as shown. The light changes direction and produces a spectrum of colours. Which term is used to describe the production of the spectrum of colours?

Two plane mirrors are placed at some angle. There are five images formed, when an object is placed symmetrically between them, the angle between the mirrors is:

If for angle of incidence, the incident ray and reflected ray from two mirrors be parallel to each other, then angle between two plane mirrors will be?
