How does the diffraction pattern change as the distance between the laser and the diffraction grating changes? How does the pattern change as the distance between the grating and the projection screen changes? (1 point)
Record your measurements and calculations in the tables below. (4 points)
The average measured wavelength is: (2 points)
The nominal wavelength (recorded on the laser) is: (1 point)
The percent difference between the measured and nominal laser wavelength is: (2 points)
Record your measurements and calculations in the tables below. (16 points)
Were your measurements of the wavelength of laser and LED light consistent with the visible spectrum? Explain. (2 points)

A monochromatic beam of light shines on a diffraction grating that has 1000 lines per mm. The screen is placed 25 cm from the grating and is parallel to it. A first order fringe is formed 10 cm from the central image. What is the wavelength of the light? Is the light visible? What part of the electromagnetic spectrum is it? Show all work. (2 points)
