1. Coherent light of wavelength 525 nm passes through two thin slits that are 0.0415 mm apart and falls on a screen 75.0 cm away. How far away from the central bright fringe on the screen is

a.) the fifth bright fringe (not counting the central bright fringe)

b.) the eighth dark fringe

2. Red light of wavelength 633 nm from a helium-neon laser passes through a slit 0.350 mm wide. The diffraction pattern is observed on a screen 3.00 m away. Define the width of a bright fringe as the distance between the minima on either side.

a.) What is the width of the central bright fringe?

b.) What is the width of the first bright fringe on either side of the central one?

Light of wavelength 600 nm passes though two slits separated by 0.25 mm and is observed on a screen 1.3 m behind the slits. The location of the central maximum is marked on the screen and labeled y = 0. A .At what distance, on either side of y = 0, are the m = 1 bright fringes? B.A very thin piece of glass is then placed in one slit. Because light travels slower in glass than in air, the...

Light of wavelength 600 nm passes though two slits separated by 0.25mm and is observed on a screen 1.1m behind the slits. The location of the central maximum is marked on the screen and labeled y = 0. A very thin piece of glass is then placed in one slit. Because light travels slower in glass than in air, the wave passing through the glass is delayed by 5.0

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.

Light with wavelength 530 nm in air (n = 1) passes through a soap bubble (n = 1.33), where its wavelength becomes ≈ 400 nm. A What is the phase difference between a light wave reflected off the surface of the bubble and one that passes into it before being reflected? B The thickness of the bubble is 100 nm. Does this lead to constructive or destructive interference? C What would happen for a soap film covering a glass surface...
