(a)

To determine

The critical angle for total internal reflection of sound at the concrete-air boundary.

Sound passes from limestone, where it moves at a speedof 4000 m/s, into another unknown material. The angle of incidence at the interface is 24° and the angle of refraction in the unknown material is 38°. (a) Calculate the speed of sound in this material. (b) Draw pictures of each situation showing the interference between the media, the normal line, the incident, reflected and refracted rays and the angles of these rays to the normal line.
A nearly perfect paraboloidal mirror has a residual RMS surface error of /40, where A is the wavelength of light. The mirror focuses light from a distant star on axis. What is the resulting wavefront error after the reflection from the mirror if one neglects the effect of atmospheric seeing? Find Strehl ratio for the mirror and the amount of energy concentrated in the central maximum of the star image.
Astronauts placed a mirror on the surface of the Moon to be used for optical measurements of the precise distance to the moon. Visible light is sent from the Earth and is reflected back from the moon. If the mirror has a diameter of 30 cm, roughly how large is the beam of reflected light that reaches Earth? The distance from the Earth to the Moon is 3.8×108 meters. You can assume the light from Earth is a plane wave when it strikes the mirror.
