Light of wavelength lambda passes through a single slit of width W and forms a d

Question

Light of wavelength lambda passes through a single slit of width W and forms a diffraction pattern on a viewing screen. If this light is then replaced by light of wavelength 2 lambda, the original diffraction pattern is exactly reproduced if the width of the slit. is changed to ;1/4W is changed to 1/2W is changed to 2W is changed to 4W remains the same-no change is necessary Resolving Power Suppose that you are using a microscope to view two closely spaced cells. For a given lens diameter, which color of light would you use to achieve the best possible resolving power? Red Yellow Green Blue All the colors give the same

Explanation / Answer

ym = mL/W

if ' = 2, ym no change, so /W = '/W'

W' = 2W

answer: (c)
