You have a source of white light at the bottom of a pool of water. Describe how you would use total internal reflection to filter blue and violet light from being refracted into the air above the pool. Be quantitative. Assume that this is a strange kind of water and use the indices as given below. Assume the index of refraction for all wavelengths of light in air is the same 1.00 .

Assume that the intensity of solar radiation incident on the cloudtops of the Earth is 1340 W/m^2. Calc the total power radiated by the Sun, taking the average Earth-sun separation to be 1.496 * 10^11 m.
In the process of changing a flat tire, a motorist uses a hydraulic jack. She begins by applying a force of 41 N to the input piston, determine the force that the output plunger applies to the car
A 4.5kg dog stands on an 18 kg flatboat at distance D = 6.10m from the shore. It walks 2.4 m along the boat toward shore and then stops. Assuming no friction between the boat and the water, find how far the dog is then from the shore.
