For better results, actual spectrometer makes use of?
Correct answer: B. Diffraction grating
- A. Capacitors
- B. Diffraction grating
- C. Mica window
- D. Polarizers
Explanation
Diffraction gratings are widely used in spectrometers to disperse light into its constituent wavelengths. They consist of a surface with many closely spaced parallel grooves that cause light to diffract, separating it into its spectral components. This allows for the analysis of different wavelengths present in a light source. So, option B is correct.

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.

A 16 cm long image of an object is formed by a convex lens on a screen placed normal to its principal axis. On moving the lens towards the screen, without changing the positions of the object and the screen, a 9 cm long image is formed again on the screen. The size of the object is:
