When light passes through a prism of glass, 1. refraction changes the directions of different colors or wavelengths of light. 2. the prism absorbs colors from different parts of the broad beam coming out of the prism, leaving the complementary colors that we see. 3. different colors are caused by multiple reflections within the prism and the resulting interference between the beams. 4. the prism adds colors to different parts of the outgoing and broadly scattered beam?

Aball has an initial velocity of 3 m/s. if there is no friction, what is the highest it could roll?

It may seem strange that the selected velocity does not depend on either the mass or the charge of the particle. (for example, would the velocity of a neutral particle be selected by passage through this device? ) the explanation of this is that the mass and the charge control the resolution of the device--particles with the wrong velocity will be accelerated away from the straight line and will not pass through the exit slit. if the acceleration depends strongly on the velocity, then particles with just slightly wrong velocities will feel a substantial transverse acceleration and will not exit the selector. because the acc

Is the number of complete movements of a wave per second.
