Question

A scientist is observing a bacteria through a compound microscope. For better analysis and to improve its resolving power he should (Select the best option)\

Professor PC Thomas Classes · Answer

(b) : Resolving power of microscope is given by 
$ 	ext { R.P }=\frac{2 \mu \sin 	heta}{1.22 \lambda} $ 
where, $\mu$ is the refractive index of medium between object and objective lens and $\lambda$ is wavelength of light used.\ So, on increasing the resolving power, $\mu$ should be increased.\
