Answer

Choice D.

Work Step by Step

Equation 25-9 shows that the resolving power of a microscope is approximately equal to the wavelength of the radiation being used. In other words, it’s impossible to resolve details that are about a factor of two smaller than the wavelength of the light. Molecular structures are hundreds of times smaller than the wavelength of visible light. X-rays can be used to resolve them.
