Please answer this question I don't know how to do it.

Energy flows from the producer level to the level. is called

Light traveling in water, nwater = 1.33, strikes a plastic block at an angle of incidence of 51.4°; part of the beam is reflected and part is refracted. if the index of refraction of the plastic is 2.0, what is the angle made by the reflected and refracted beams?

The law of reflection states that the angle of reflection is equal to the angle of
