White light is incident onto a 30 prism at the 40 angle shown in FIGURE P35.41. Violet light emerges perpendicular to the rear face of the prism. The index of refraction of violet light in this glass is 2.0% larger than the index of refraction of red light. At what angle f does red light emerge from the rear face?
Day 15 2/8/2016 Phys 5b HW #1 asked to calculate how long will it take for the displacement to decrease one percent to its original value, referring to the exponential envelope. Pretend as if the sinusoidal didn’t exist Reading: 15.2, 15.5, 15.7, 16.1, 16.2 Review: Standing Waves by adding up two waves of the same amplitude, wavelength, and frequency, but propagating in opposite direction, y 1, t) = Asin(kx wt) and y 2x, t) = Asin(kx + wt), we obtained a standing wave, and we have shown that its mode of vibration depend on the boundary conditions as follows Closed Closed Standing Wave Pattern λ = 2L n = 1, 2, 3, … n n P n
