Unpolarized light passes through two Polaroid sheets. The transmission axis of the analyzer builds an angle of 45.8° with the axis of the polarizer.
1. What fraction of the original unpolarized light is transmitted through the analyzer?
2. What fraction of the original light is absorbed by the analyzer?
Two waves traveling in opposite directions along a string fixed at both ends create a standing wave described by y(x, t) = 0.01 sin(44x)cos(1090t). The string has a linear mass density of 0.01 kg/m, and the tension in the string is supplied by a m..
