The slit separation (with the slit width unchanged). The slit width (with the slit separation unchanged).
You are using a double-slit interference experiment to determine the wavelength of a laser. Make all necessary measurements with associated uncertainties. Use your data to find the wavelength and the uncertainty in the wavelength. Explain your reasoning clearly.
The color or intensity of light is represented by the spots on the screen.

Light from a fluorescent lamp goes through a diffraction grating with 600 lines/mm. The middle bright spot will be at degrees for all wavelengths. Determine the angles for the second order bright spots for red light (λ=650 nm) and blue light (λ=450 nm). Calculate the wavelength of visible light that leaves the grating at an angle of 30 degrees.
7) Two slits 0.7mm apart are illuminated by a laser with a wavelength of 632 nm. How far apart are the bright spots on a wall 1 m from the slits?
8) Albert Einstein left behind many notable quotations in addition to his brilliant theories. Find a website that lists some of Einstein's famous quotations and choose at least one that you particularly like. Pick one that has to do with physics or math, and another that relates to life in general.
