1. What is the avg total energy density in the wave given: Freq=6.15E14 hz travelling in a vacuum (c=3.0x10^8) the wave strikes a 9cm^2 surface oriented perpindicular to the wave deositing 1.35 mW of average power. The wavelength of the wave is 88 nm
2. Unpolarized light passes through two polarizers. The inensity of light coming out from the second polarizer is S2=33% of the intensity of te unpolarized light S0. What is the angle between the transmission axes of the polarizers.
