Question

Which of the following instrument is used to study the phenomenon of Dispersion of Light?
1. Spectrometer
2. Photometer
3. Microscope
4. Anemometer

Answer 1

Correct Answer - Option 1 : Spectrometer

The correct answer is Spectrometer.

• Dispersion can be defined as the phenomenon associated with the propagation of individual waves at speeds that depend on their wavelengths.

• A spectrometer is a scientific instrument that is used to separate and measure spectral components of dispersion.
• It is an optical device for measuring wavelengths, deviation of refracted rays, and angles between faces of a prism.
• It consists of a slit through which light passes, a prism that deviates the light, and a telescope through which the deviated light is viewed and examined.
