Sunlight strikes a piece of crown glass at an angle of incidence of 37.1o. Calculate the difference in the angle of refraction between a orange (610 nm) and a green (550 nm) ray within the glass. The index of refraction is n

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.
