Questions on Interference and Diffraction

1. What does it mean when we say that two waves are coherent?
2. What is a standing wave?
3. Can traveling waves be used to generate standing waves?
4. In the case of a vibrating string, what is the relation between the wave's wavelength and the length of a string for a standing wave to be supported? Is this condition always satisfied?
5. What are interference maxima and interference minima for a standing wave on a string? Draw a diagram to show these.
6. What are resonant frequencies?
7. What happens to a string when forced to oscillate at a resonant frequency?
8. What are the components that make up a Michelson interferometer?
9. How does a Michelson interferometer produce interference patterns?
10. What could be some of the uses of a Michelson interferometer?
