Question 386: Waves Optics

Question

When wavelength of light used in optical instruments A and B are 4500$$\mathop A\limits^o $$ and 6000$$\mathop A\limits^o $$ respectively, the ratio of resolving power of A to B will be

Accepted Answer

The resolving power of optical instruments is inversely proportional to the wavelength of light used, as represented by the formula:
$ 	ext{Resolving Power} \propto \frac{1}{\lambda} $
Given that the wavelengths for optical instruments A and B are $ \lambda_A = 4500 $ ÃÂ and $ \lambda_B = 6000 $ ÃÂ, the ratio of their resolving powers can be calculated as follows:
$ \frac{(	ext{Resolving Power})_A}{(	ext{Resolving Power})_B} = \frac{\lambda_B}{\lambda_A} = \frac{6000}{4500} = \frac{4}{3} $
Therefore, the ratio of resolving power for instrument A to B is $ 4:3 $.
