Problem 87

For any type of wave that reaches a boundary beyond which its speed is increased, there is a maximum incident angle if there is to be a transmitted refracted wave. This maximum incident angle corresponds to an angle of refraction equal to 90. If all the wave is reflected at the boundary and none is refracted, because refraction would correspond to (where is the angle of refraction), which is impossible. This phenomenon is referred to as total internal reflection. (a) Find a formula for using the law of refraction, Eq. 1120. (b) How far from the bank should a trout fisherman stand (Fig. 1161) so trout wont be frightened by his voice (1.8 m above the ground)? The speed of sound is about in air and 1440 ms in water.
