Suppose that Young’s experiment is performed with light of wavelength 581 nm. The slits are 1.54 mm apart, and the viewing screen is 2.78 m from the slits. How far apart are the bright fringes in centimeters?

A transformer has 700 primary turns and 7.7 secondary turns. If Vp is 120 V (rms), what is Vs with an open circuit? 

In the figure, light is incident at angle θ1 = 39˚ on a boundary between two transparent materials. Some of the light travels down through the next three layers of transparent materials, while some of it reflects upward and then escapes into the air. If n1 = 1.26, n2 = 1.36, n3 = 1.34 and n4 = 1.43, what is the value of θ5

Monochromatic light of wavelength 679 nm illuminates two parallel narrow slits 7.24 μm apart. Calculate the angular deviation of the third-order (for m = 3) bright fringe in radians.

The figure depicts a simplistic optical fiber: a plastic core (n1 = 1.60) is surrounded by a plastic sheath (n2 = 1.44). A light ray is incident on one end of the fiber at angle θ. The rays is to undergo total internal reflection at point A, where it encounters the core-sheath boundary. (Thus there is no loss of light through that boundary.) What is the maximum value of θ that allows total internal reflection at A?

A rectangular loop (area = 0.55 m2) turns in a uniform magnetic field, B = 0.20 T. When the angle between the field and the normal to the plane of the loop is π/2 rad and increasing at 3.9 rad/s, what emf is induced in the loop?
