HELP Light rays travel from one medium into another and refract away from the
boundary. What changes about the light to cause this refraction?

A. Its speed decreases.
B. Its speed increases.
C. Its frequency increases.
D. Its frequency decreases.

Convection occurs when thermal energy is transferred by the movement of

The law of reflection states that the angle of reflection is equal to the angle of

Water is siphoned from a large tank and discharges into the atmosphere through a 50-mm diameter tube. the end of the tube is b = 2.6 m below the tank bottom which is a = 6.7 m deep, and viscous effects are negligible. determine the maximum height h over which the water can be siphoned without cavitation occurring. atmospheric pressure is 101.4 kpa, and the water vapor pressure is 1.79 kpa (absolute). report your answer in meters to two decimal places.
