A converging lens of a diamond and a lens of crown glass have the same shape?
Which lens will have the greater focal length? Explain your answer.
Index of refraction of diamond = 2.42
Index of refraction of crown glass = 1.52
Both are converging lenses.
You don't need to actually figure out the FLs, since this is a greater than/less than question. The lower index of refraction gives less convergence which results in a longer FL.
