In two-slit interference, if the slit separation is 14 $\mu$m and the slit widths are each 2.0 $\mu$m, how many two-slit maxima are in the central peak of the diffraction envelope?

If a beam of white light passes through a diffraction grating with vertical lines, the light is dispersed into rainbow colors on the right and left. If a glass prism disperses white light to the right into a rainbow, how does the sequence of colors compare with that produced on the right by a diffraction grating?

The micrometer (1 $\mu$m) is often called the micron. How many microns make up 1.0 km?

A diffraction grating with 600 lines/mm is illuminated with light of wavelength 510 nm. A very wide viewing screen is 2.0 m behind the grating. a. What is the dista nce between the two m = 1 bright fringes? b. How many bright fringes ca n be seen on the screen?

A double-slit system with individual slit widths of 0.030 mm and a slit separation of 0.18 mm is illuminated with 500 nm light directed perpendicular to the plane of the slits. What is the total number of complete bright fringes appearing between the two first-order minima of the diffraction pattern? (Do not count the fringes that coincide with the minima of the diffraction pattern.)
