A laser beam having 652 nm wavelength and 10microns width is fired at a very thin steel plate, which has twoslits in it. Both slits are very narrow, and they are 1 micronsapart. A diffraction pattern is observed on a screen 1 meter beyondthe plate.

a) What is the spacing of the bright spotsobserved on the screen?
b) As time passes, the plate heats up from thepowerful laser, reaching 300°C. What is the new spacing of thebright spots on the screen?
