Light of wavelength 589 nm is used to view an object under a microscope. The aperture of the objective has a diameter of 0.900 cm. Find What is the maximum limit of rewolution for this microscope Unsing visible light of any wavelength you desire.

Answer»

SOLUTION :To obtain the smallest angle corresponding to the maximum limit of resolution, we have to use the shortest wavelength `(lambda= 400 NM)` in the visible SPECTRUM.
Limiting angle of resolution
`triangle THETA = 1.22((400xx10^(-9)m)/(0.900xx10^(-2)m)) rad`
`= 5.42xx 10^(-5)rad`
