A Plane polarized light is incident on a piece of quartz cut parallel to its axis. Evaluate the least thickness for which ordinary ray and extraordinary ray combine to form the plane polarized light. Given µ0 = 1.5442, µE = 1.5533, λ = 5×10-5 cm.
A bat emits a sound whose frequency is 142 kHz. The speed of sound in air at 20.0°C is 343 m/s. However, the air temperature is 35°C, so the speed of sound is not 343 m/s. Find the
