How can resolving power of the instrument be increased?
AnswerClick to flip back
A
use UV light
B
immerse in oil
💡 Explanation:
Resolving power for the instrument is found to be $\dfrac{\mu\sin\theta}{0.61\lambda}$ , UV light has short wavelength, hence higher resolving power. Oil is optically denser than air, that is, its $\mu$ is greater than that of air. Thus immersing in oil would increase the resolving power.
