Suppose you use the same double slit to perform Young’s double-slit experiment in air and then repeat the experiment in water. Do the angles to the same parts of the interference pattern get larger or smaller? Does the color of the light change? Explain.

Hi I would really appreciate some help on thus question. A red laser, shining on a double slit, creates the pattern shown in the figure below at the center of a screen placed 1.90 m on the opposite side of the double slit from the laser. If the laser wavelength is 632 nm, what is the distance between the two slits in the double slit? (NOTE: final answer should be in units of nm) Thank you in advanced for the help!

This question is regarding the experiment ’Diffraction and Interference of Light’. a) In a diffraction experiment for a given slit and a given slit-screen distance,would the distance between the dark fringes increase or decrease when a blue laser is replaced with a red laser? Use equations to argue why, in no more than two sentences (Hint: wavelength λblue = 470nm, λred = 700 b) Draw the pattern you observe for two slit interference. Mark clearly the diffraction and the interference parts of this pattern. c) How will the pattern change? When I change the distance between the slits?
We have all seen colorful soap bubbles (I hope) as children. The interesting patterns of color that arise in the bubble are a consequence of ambient light passing through the soap film, reflecting or transmitting off of the boundaries between soap and air, and constructively (or destructively)interfering. Let d denote the unknown soap bubble film thickness. The index of refraction of air n_air≈1, while the index of refraction in the soap film is n≈1.3. 1.1. Determine the criterion on the soap film thickness d to have constructive interference between incident and reflected light of wavelengthλ. Assume it is an incident normally on the soap film. 1.2.Visible light hasλ≈600 nm in air. Given that visible light can constructively interfere with the soap film, estimate its thickness.
Broad spectrum white light containing wavelengths from 420 nm to 730 nm falls on arefraction grating with 7900 slits / cm. How wide is the first order spectrum on a screen3.1 m away? (Hint: solve for theta for first order fringe for each wavelength, then usetrig to solve for distance from straight through direction location on screen to positionof each wavelength on screen. Subtract these distances to get width of first orderspectrum).
