- Mirror M, in the figure below is moved through a displacement AL. During this displacement, 240 fringe reversals (formation of successive dark or bright bands) are counted. The light being used has a wavelength of 634.8 nm. Calculate the displacement AL. 39.6 Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. µm A single ray of light is split into two rays by mirror M, which is called a beam splitter. Light source The path difference between the two rays is varied with the adjustable mirror M1. M1 Telescope Mo As M1 is moved, an interference M2 pattern changes in the field of view. Need Help?

You are designing a diffraction grating, and have decided that when the grating is used with a white light source, both the entire first and second order rainbows (visible part of the spectrum) should be visible within 30° of the central maximum. In order to have the machine shop produce your grating, you need to calculate the line density of the grating. You also wonder how many complete rainbows could potentially be seen with this grating. Your textbook says that the visible light has wavelengths between 400 and 700 nm.
