The focal length of the concave lens is taken as negative.
True
False
According to the sign convention, the focal length of the concave lens is taken as negative since it lies on its left side as shown
Why focal length of convex mirror and convex lens is positive while concave mirror and concave lens negative?
A concave lens made of material of refractive index 1.6 is immersed in a medium of refractive index 2.0. The two surfaces of the concave lens have the same radius of curvature 0.2 m. The lens will behave as a
