Two prisms with the same angle but different indices of refraction are put together to form a parallel sided block of glass (see the figure). The index of the first prism is n1 = 1.54 and that of the second prism is n2 = 1.71. A laser beam is normally incident on the first prism. What angle will the emerging beam make with the incident beam? (Compute to the nearest 0.1deg)
The sketch at the left shows a square loop of wire. Its resistance is 5 ohm. Its dimensions are shown: a = 4.0 cm, b = 5.0 cm. The nearby wire carries a current of 10.0 A. What is the magnitude of the magnetic flux in the loop of wire?
A wire of radius 0.5 cm carries a current of 150 A that is uniformly distributed over its cross-sectional area. find the magnetic field at the surface of the wire
