Amichelson interferometer uses red light with a wavelength of 656.45 nm from a hydrogen discharge lamp. part a how many bright-dark-bright fringe shifts are observed if mirror m2 is moved 1.7000 cm ? express your answer using five significant figures.

51793 bright-dark-bright fringe shifts are observed when the mirror M2 moves through 1.7cm

Explanation:

The number of maxima appearing when the mirror M moves through distance \Delta L is given as follows,

Here,

= is the distance moved by the mirror M

is the wavelenght of the light used.

= 0.017m

Therefore, 51793 bright-dark-bright fringe shifts are observed when the mirror M2 moves through 1.7

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
