For better resolution and clear visibility through microscope, we use:
Correct answer: B. Shorter wavelength light
- A. Longer wavelength light
- B. Shorter wavelength light
- C. Wavelength has no effect
- D. It depends only on the design of the microscope not on a light
Explanation
The resolving power of a microscope is determined by its ability to distinguish between two closely spaced objects. According to the Rayleigh criterion, which describes the limit of resolution, smaller wavelengths of light contribute to better resolution.

About Optics
Light is studied through reflection, refraction, dispersion, interference, diffraction and polarization, linking ray behavior with its wave nature. Questions may involve mirrors, lenses, optical instruments, refractive index and image formation, while geometrical optics deals with rays and wave optics explains effects such as interference and diffraction.
