Question

Obtain lens maker’s formula and mention its significance.​

Answer 1

Answer:

If the refractive index of the lens is and it is placed in air, then n2 = n and n1 = 1 equation (4) becomes, The above equation is called the lens maker's formula, because it tells the lens manufactures what curvature is needed to make a lens of desired focal length with a material of particular refractive index.
