Suppose you illuminate two thin slits by monochromatic coherent light in air and find that they produce their first interference minima at \pm 35.09 degrees on either side of the central bright spot. You then immerse these slits in a transparent liquid and illuminate them with the same light. Now you find that the first minima occur at \pm 19.48 degrees instead.
a) What is the index of refraction of this liquid?
Express your answer using four significant figures.

Consider two coherent monochromatic sources of light of wavelength (lambda) centered at the origin and located at (0, 0,-d) and (0,0,+d). Show that the locus of points, satisfying either the condition for constructive or destructive interference, form a family of hyperboloids of revolution (one for each value of m) with the foci located at the sources. Do this by deriving the equation for the hyperboloid of revolution in Cartesian coordinates (1pt) and locating the focus points (0.5pts). Additionally, what does...

In Young’s experiment, monochromatic light of wavelength 600 nm shines on two slits separated by 0.3 mm, producing an interference pattern on a screen that is 2.0 m away.
