In Youngs double slit experiment the distance between the screen and the slits is 1.00 m. The slits separation is 0.050 mm and the distance between the central bright and first order bright is found to be 8.00 mm. Calculate the wavelength of the light used.

Gordon is going for a run through the park, but it is cold outside. the low outside temperature could affect his personal safety.

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.
