A convex lens brings parallel rays entering it to a single crossing point on the far side. What is such a lens called?
AA diverging lens
BA converging lens
CA corner reflector
DA polarising filter
Answer & Solution
Correct answer: B. A converging lens
1. A convex lens brings parallel rays entering it to a single crossing point on the far side.
2. This converging effect on light rays is exactly why it is called a converging lens.
3. A diverging lens has the opposite, concave shape and spreads rays apart instead.
