    How do you find speed given the beat frequency?

    Hi! I am assuming you are referring to the doppler effect if so I would assume you would use fapparent = (v/(vs+v))f. Would this be sufficient enough to solve this question?

    How do you find speed given the beat frequency?

    Homework Statement Using a radar gun, you emit radar waves at a frequency of 2.6 GHz that bounce off of a moving tennis ball and recombine with the original waves. This produces a beat frequency of 730 Hz. How fast was the tennis ball moving? Homework Equations fbeat = fa - fb v=λf f=1/TThe...

    Which formulas are appropriate for calculating intensity?

    Homework Statement Monochromatic plane waves of wavelength 537nm are incident on two narrow slits and produce an interference pattern on a wall 3.1m away. The slits are spaced 26 micrometers apart and are 5.7 micrometers wide each. What is the ratio of intensity to that of the central fringe a...
