A grating has 1040 slits/cm. At what angle will a red laser of 630-nm wavelength will produce a second-order maximum when falling on this grating? (a) Determine the linear distance (in cm) of the 2nd order bright spot from the center of the pattern on a screen 1.5-m away. (b) Draw a diagram indicating the center, 1st and 2nd order bright spots - Indicate all the parameters. (c) Instead, if a green laser shines on the above gating - indicate the location for the center, 1st and 2nd order bright spots on the same diagram.
