A diverging lens is also called:
AConvex lens
BConcave lens
CPlano-convex lens
DBiconvex lens
Answer & Solution
Correct answer: B. Concave lens
1. A diverging lens spreads parallel rays away from a central axis.
2. Such a lens is thinner at the centre and thicker at the edges — i.e. concave.
3. Convex lenses converge rays.
