![]() Can the lines in a diffraction grating be too close together to be useful as a spectroscopic tool for visible light? If so, what type of EM radiation would the grating be suitable for? Explain.ġ5. What are the advantages of a diffraction grating over a prism in dispersing light for spectral analysis?ġ4. What is the advantage of a diffraction grating over a double slit in dispersing light into a spectrum?ġ3. This double slit interference pattern also shows signs of single slit interference. Is this a single slit or double slit characteristic? Which is smaller, the slit width or the separation between slits? Explain your responses. Is this a double slit or single slit characteristic? Note that some of the bright spots are dim on either side of the center. Note that the bright spots are evenly spaced. ![]() The pattern is actually a combination of single slit and double slit interference. The figrue shows the central part of the interference pattern for a pure wavelength of red light projected onto a double slit. Is it possible to create a situation in which there is only destructive interference? Explain.ġ1. Do the angles to the same parts of the interference pattern get larger or smaller? Does the color of the light change? Explain.ġ0. Suppose you use the same double slit to perform Young’s double slit experiment in air and then repeat the experiment in water. Would the same pattern be obtained for two independent sources of light, such as the headlights of a distant car? Explain.ĩ. Young’s double slit experiment breaks a single light beam into two sources.
