Does a fatter converging lens refract light more or less than a thinner one? Explain.?

Question

Please be brief, clear and precise in explaining your answer. Thanks.

Answer 1

All other  things being equal it will refract slightly less if both sides of the lens are convex.

The power (or ability to refract) of a lens is mainly determined by the refractive index of the glass and the curvature of the two surfaces.  However, a secondary effect is that the power is slightly reduced for a biconvex lens as it gets thicker.

It is not the thickness that matters, however

It is the angle at which the incident light strikes the material of the lens

A fatter lens has a bigger angle
