Question

power of concave lenses is always..............​

Answer 1

Answer:

HI MATE !

• Concave lens surfaces have a virtual and therefore negative radius of curvature.

• The convention signs used for focal length are also used for optical power.

• Convex lenses, which have a real focus, have a positive focal length and optical power.

• Concave lenses, with a virtual focus, have a negative focal length and optical power.

The power of concave lenses is always negative.
