The index of refraction for crown glass is 1.512 at a wavelength of 660 nm (red), whereas its index of refraction is 1.530 at a wavelength of 410 nm (violet). If both wavelengths are incident on a slab of crown glass at the same angle of incidence, 87.6°, what is the angle of refraction for each wavelength?
1. red = ?
2. violet = ?

At t = 0 a grinding wheel has an angular velocity of 27.0 rad/s. It has a constant angular acceleration of 32.0 rad/s2 until a circuit breaker trips at t = 2s. From then on, it turns by 432 rad as it coasts to a stop at constant angular accelerati..
Two unequal point charges q1 and q2 are held in place unconnected from each other. A point charge Q is placed somewhere between them at a point where it remains stationary when free. From this observation, we can conclude that q1 and q2 must eithe..
