Laser light is shown through a diffraction grating with a line density of 880 lines per mm. The 2nd order maximum is measured to be 1.5 meters away from the center on a screen that is 3.0 meters from the diffraction grating.

a) What is the wavelength of the laser?

b) How many laser dots are visible on the screen (assuming that the wall is large enough)?

c) What is the total distance between the two first order maxima on the wall?
