Answer: Options not given.

The correct option is one quarter wavelengths.

Here are the options.

a. one wavelength

b. half a wavelength

c. one-quarter wavelength

d. it depends on the wavelength

e. it depends on which mirror is moved

It must be moved by one quarter wavelength

Explanation:

The standard way to use oMichelson apparatus is to first measure the wavelength of the incident light. One of the mirrors is moved nearer or farther away while observing the fringe pattern. one of the mirrors at the end of an arm must be moved by one quarter wavelength in order to shift the pattern by half a fringe,
