Transcribed Image Text:Part A
A plate of glass with parallel faces having a refractive
index of 1.54 is resting on the surface of water in a tank.
A ray of light coming from above in air makes an angle of
incidence 36.0 ° with the normal to the top surface of the
glass. (Figure 1)
What angle 03 does the ray refracted into the water make with the normal to the surface? Use 1.33 for the index of
refraction of water.
Express your answer in degrees.
