$[-/1$ Points$]$

$$ SERCP$1125\mathrm{.}7.$P$\mathrm{.}052.N=1,700$ times.

$($a$)$ Determine the wavelength of the light.

$q,$ nm

What color is it$?$

orange

red

blue

yellow

purple

green

$($b$)$ If monochromatic red light is used instead and the mirror is moved the same distance, would $N$ be larger or smaller?

$N_{\text{c}\text{y}\text{c}\text{l}\text{e}\text{s}}$ would be the same

$N_{\text{c}\text{y}\text{c}\text{l}\text{e}\text{s}}$ would be larger

$N_{\text{c}\text{y}\text{c}\text{l}\text{e}\text{s}}$ would be smaller
