Laser light is shown through a diffraction grating with a line density of 300 lines /mm . The 2nd order maximum is measured to be 2.30 m away from the center on a screen that is 4.52 m from the diffraction grating.
1. What is the wavelength of the laser? =
2. How many laser dots are visible on the screen (assuming that the wall is large enough)? =
3. What is the total distance between the two first order maxima on the wall? =
4. If the laser were replaced with a 605 laser instead, at what distance from the central maximum would the second order be located?
