The formula for the resolving power (resolution distance)of a lens is λ/2NA (wavelength /2 x numerical aperture).What does this say about resolving power
A)The smaller the wavelength,the greater the resolving power of the lens.
B)Resolving power is not related to the lens' numerical aperture.
C)We cannot precisely calculate a lens resolving power.
D)A larger resolving power is indicative of a better lens.

Question

Quizplus · Accepted Answer

The formula for resolving power shows that resolving power is directly proportional to the wavelength of light and inversely proportional to the numerical aperture of the lens. Therefore, smaller wavelengths result in greater resolving power, and increasing numerical aperture also increases resolving power.
