Question

please answer asap and use Nair=1 Nwater=1.333 and c=3x10^8 m/s

4) Fig. 4 A light ray in water of wavelength 529nm is incident on flat, rectangular piece of transparent plastic (n 1.49) that is floating on a pool of water (n= 1.333). The ray from the water strikes the bottom of the plastic at an angle of 40.0° from the normal line. What happens to the ray when it hits the top edge of the plastic? (give all numeric quantities)

Answer 1

ウ 40 on, = 1.33 1.49 58.+5

As wavelength is inversely proportional to refractive index of medium so wavelength also increases.

please rate it up thanks :)
