Wavelength Measurement | MCQs

Explanation

The device that can be used for precise measurement of wavelength is a Michelson Interferometer. 

A Michelson interferometer uses the interference of light waves to measure very small distances, including wavelengths, with high accuracy. 

Explanation

The Angstrom (Å) is commonly used to measure wavelengths of light, where

1 Å = 10⁻¹⁰ meters.

Light wavelengths typically range from 4000 Å to 7000 Å.
