The separation between two microscopic particles is measured

{P_A}

and

{P_B}

by two different lights of wavelength

2000\,\,\mathop \mathrm{A}\limits^ \circ

and

3000\,\,\mathop \mathrm{A}\limits^ \circ

respectively, then

View answer and explanation

Correct option: B

{P_A} < {P_B}

Option B is correct. Resolving power is inversely proportional to the wavelength of light used. Therefore, smaller wavelength light (2000 Å) will have better resolving power and thus smaller resolvable distance.
