Answers
Answer:
Light from the Sun falling on convex lens will converge at a point called as principal focus.
Explanation:
1. A convex lens can be regarded as made of a very large number of portions of triangular prisms.
2. The bases of these prisms are towards the central thicker portion of the lens.
3. A ray of light passing through a prism bends towards its base.
Hence, a convex lens converges the light rays.
Concepts:
1. Convex lens :
A lens having both spherical surfaces puffed up outwards is called a convex lens.
2. It is thicker in the middle than at the edges.
3. A convex lens is also called a converging lens.
4. Principal focus :
When light rays parallel to the principal axis are incident on a convex lens, they converge at a point on the principal axis. This point is called the principal focus.
It is denoted by F.
Answer:
focus
Explanation:
the point where all the light rays meet at a point is called focus point
it converges the light rays to the point so it is also called a converging lens
