Question

Using the Doppler Waves simulation set the unshifted wavelength of the light to 355 nm. Set the v/c slider to -0.02 and start the simulation, pausing after waves reach the far side of the screen. With the simulation paused use the distance indicator in the simulation to measure the distance between two successive crests along the dotted line to the right of the moving object. This distance is the apparent wavelength of the light λa.

λa = ________ nm

Using the relationship Determine your measured v/c v/c (measured with slider at -0.02) = ___________(record your answer to at least 2 significant figures)

Now reset the simulation and set the v/c slider to -0.081 and repeat the steps above v/c (measured with slider at -0.081) = ___________ (record your answer to at least 2 significant figures)

Answer 1

Using the formula

v/c (measured with slider at -0.02) = -0.02

v/c slider to -0.081 and repeat the steps above v/c (measured with slider at -0.081) = -0.081
