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

it would be kevlar ^^

energy stored in the capacitor= 9.72 x 10⁻⁴ j

explanation:

the energy stored in the capacitor is given by

e= 1/2 c v²

e= energy stored

c= capacitance= 1.5 µc= 1.5 x 10⁻⁶f

v= potential difference=36 v

so energy stored= e= 1/2 (1.5 x 10⁻⁶) (36)²

energy stored= 9.72 x 10⁻⁴j
