a) An oil slick on water is 108 nm thick and illuminated by white light incident perpendicular to its surface. What color does the oil appear (what is the most constructively reflected wavelength, in nanometers), given its index of refraction is 1.41? (Assume the index of refraction of water is 1.33.) wavelength________ nm b)A ruby laser beam is reflected from the surface of a CD onto a wall. The brightest spot is the reflected beam at an angle equal to...

Part B & C
When light of a wavelength lambda = 433 nm is incident on a diffraction grating the first maximum after the center one is found to occur at an angle of theta_1 = 8.5 degrees. (a) Write an expression for the grating's line density, n, in terms of the given quantities. (b) Calculate this spacing in lines per centimeter? n = (c) Find the angle of the second order intensity maximum, theta_2, in degrees.

A laser beam of wavelength 600 nm falls on a grating having 4000 lines per cm. If the screen is 2.00 m away from the grating, how far apart will be the two first order images. (The answer says it is .98m but I got .49m and I have no clue what I did wrong.)
