Question

A ray of white light moves through the air and strikes the surface of water in a beaker. The index of refraction of the water is 1.33 and the angle of incidence is 30º. All of the following are true EXCEPT:I. the angle of reflection is 30º.II. the angle of refraction is 30º.III. total internal reflection will result, depending on the critical angle.

Answer 1

Answer:

La frecuencia será la misma en los dos medios, y en el vacio, no varia.
