Light travelling in air is incident onto a flat glass surface at an angle of (3.50x10^1) degrees with respect to the surface normal. If the speed of light in air is 3.00x10 m/s, and the speed of light in the glass is (1.530x10^0) x10 m/s, calculate the angle of refraction in degrees to 3 sf. incident 1 1 refracted Note: Your answer is assumed to be reduced to the highest power possible.A wave has an equation of y(x,t) = (0.193 m) cos ( (4.540x10^2)t - (7.80x10^2)x ) Assuming all parameters are in SI units, calculate the frequency of the wave in Hz to 3 sf
