Exam 35: Interference and Diffraction

A monochromatic source produces light at a wavelength of 510 nm in air. The wave then passes through water that has an index of refraction of 1.32. The frequency of the wave in the water is

The resolving power for a grating increases with an increase in

White light shining onto a grating or onto a prism is "separated" into different colors. By comparison,

"Every point in space can be regarded as a wave source" is known as

Consider a Young's double-slit experiment. the slits are separated by 1.2 mm, and the monochromatic light has a wavelength of 600 nm. The angular position of the first-order dark (minima) fringe is

In comparing two gratings, the one with the greater resolving power must invariably provide for

When light reflects from a thin film, whether or not a phase shift occurs at one or both of the reflecting surfaces, the single characteristic of the fringes that is affected by this potential change is

The angular separation between successive principal maxima for a grating decreases with increasing

An electric field phasor makes an angle of $\omega t$ relative to the x axis. As time increases the phasor rotates

The diffraction pattern produced by a single rectangular slit is known as
