A horizontal ray hitting a prism with n=1.5, tip angle α=4o. The ray will be deflected by an angle δ=(n-1)α. The ray is further reflected by a vertical mirror. Now, if I want to make the final ray becomes horizontal again, how many degree (and in what direction) should I turn the mirror?
Light propagates as transverse EM rays. The magnitude of electric field is much larger as compared to magnitude of magnetic field. We generally prefer to define light as electric f
An object located four focal lengths in front of a thin, converging lens is moved to within two focal lengths of the lens. As a result, does the size of the image produced by
A box is initially at rest on a horizontal, frictionless table. If a force of 10 Newtons acts on the box for 3 seconds, what is the momentum of the box at the end of the 3 second i
