Solution: The light refracts to an angle of 74° from the horizontal and the sound refracts to an angle of 26° from the horizontal.

I get that the beam and sound wave refract by the same amount since that both have a refractive index of 1.8 for the liquid. Also, my angle is different --> I get 69 degrees from the horizontal.

basically sin (40) = 1.8 sin (θ)

θ=21
