Submit your work to the instructor. The physics of interference and a student experiment. A student is measuring the wavelength of a narrow, monochromatic light source. The double slit has a separation of 0.15mm. A second student places markers on a screen 2.0m in front of the slits at the positions of successive dark bands in the patterns. The student finds that the dark bands are 0.56cm apart. - a. The student has met two important conditions for interference to occur. What are they? - b. Calculate the wavelength of the light source. - c. Calculate the spacing of the dark bands if a source of wavelength 600.0nm were used. (A "nm" is a nanometre, or 109m.) - d. If a student wants the spaces between the dark bands in an interference pattern to be wider apart, should the spacing between the slits increase or decrease
