A metal rod with the length of 3.0 m moves at 5.2 m/s in a region where the vertical component of the magnetic field is 0.75 T. What emf would be developed in this rod?

Which one of the following types of electromagnetic waves travels through space the fastest?

The magnetic flux through a coil changes from 2.0×10-5   T·m2{“version”:”1.1″,”math”:”2.0×10-5   T·m2″}   to   6.0×10-5  T·m2{“version”:”1.1″,”math”:”6.0×10-5  T·m2″}  in 0.20 s{“version”:”1.1″,”math”:”0.20 s”}. What emf is induced in this coil?

In a two-slit experiment, a fifth-order bright fringe is observed at an angle of 3.0°{“version”:”1.1″,”math”:”3.0°”} away from the centerline. If the wavelength of light is 550 nm{“version”:”1.1″,”math”:”550 nm”}, how far apart are the two slits?

Light of wavelength 470 nm{“version”:”1.1″,”math”:”470 nm”} in air enters a material of refractive index 2.16{“version”:”1.1″,”math”:”2.16″}.

SETI, the Search for Extraterrestrial Intelligence, listens to a range of frequencies referred to as the Water Hole. Hydrogen atoms have the lowest frequency within the Water Hole at 1420 MHz. What is the wavelength for this frequency? The speed of light is 3.00 x 108 m/s. M=106

How far does a beam of light travel in 5 s{“version”:”1.1″,”math”:”5 s”}?    (c=3×108 m/s{“version”:”1.1″,”math”:”c=3×108 m/s”})

Diamond has an index of refraction of 2.42. What is its critical angle if it is in air?

Two coherent, monochromatic beams of light are traveling through water. One beam goes through an air bubble of width d. If the two beams are combined after the air bubble, what sort of interference would occur? Take nair = 1, nwater = 1.3, and d = 4 μm. The wavelength of the light in air is λair = 480 nm. Assume that the only difference between the two beams is caused by the air bubble.

Which of the following diagrams does NOT correctly indicate two principal rays and the image of the object for the diverging or converging lens shown? (NOTE: the object is the leftmost arrow in the diagrams)
