1. Green laser light (coherent and monochromatic) of wavelength 540 nm is incident on a diffraction grating with 600 slits per mm. a. What is the distance (d) between consecutive slits? b. What is the angle to the first bright fringe? c. If the diffraction grating is 25.0cm from the screen, what will be the distance from the center fringe to first fringe (m=1)? 2. A Light from a point source 10 cm away from a converging lens passes through the lens and converges again 10 cm away from the lens on the other side to form an image. What is the focal length of the lens? 1. Green laser light (coherent and monochromatic) of wavelength 540 nm is incident on a diffraction grating with 600 slits per mm. a.
