A plano concave lens is one that has a surface that curves inward, making the lens thinner at its center than at its edges. Its effect on light is :. a.) to make it appear as if incident parallel light is coming from a point close to the lens on the opposide side from the light source
b.) the diverge in incident beam of light
c.) to converge light to a focus
d.) to make it appear as if incident parallel light is coming from a point close to the lens on the same side as the light source
