 (Extra Credit: 5 points) A dolphin is swimming toward a wall at the speed shown above.  The dolphin emits a “chirp” at 50 kHz to echo-locate the wall.  If this sound pulse is reflected back, what is the frequency of the echo received by the dolphin?  Show and explain all work.  (The bulk modulus of sea water is β = 2.31 x 109 N/m2 and the density of the seawater is ρ = 1.10 x 103 kg/m3.)

  Mirror 1 is horizontal.  Mirror 2 is tilted 25o from vertical.   A light ray is incident on Mirror 1 at the angle shown.  What is the angle of reflection of the ray with Mirror 2? In your work, draw the resultant path of the light ray as it reflects off both mirrors.
