a) Your teacher produces a light interference pattern on the wall. How will you identify whether the pattern is being created by a single, double, or multiple slit apparatus?
b) Use the single slit simulator to validate the equations learned in this activity related to single-slit diffraction. Use the simulator to obtain measurements, and then show complete calculations of the
c) When white light, composed of all wavelengths (as opposed to monochromatic light that is composed of one wavelength of light), is shone through a diffraction grating, bands of various colours appear on the screen. For example, there may be first-order (m = 1) fringes for red, orange, and yellow as well as second or third-order fringes for these colours.
In this particular case, white light is shone on a grating that is 1.00 cm wide and contains 10 000 lines. First-order fringes are produced for three colours of light at angles of 30o, 35o, and 40o. Find the wavelengths that produce first-order maxima at these angles. Find out what colours are associated with these wavelengths.
