*20. Imagine driving down a street toward a traffic light. How fast would you have to go so that the red light (700 nm) would appear green (500 nm)? What fraction of the speed of light c (c = 300,000 km/s) is this velocity?

A speeder tries to explain to the police that the yellow warning lights she was approaching on the side of the road looked green to her because of the Doppler shift. How fast would she have been traveling if yellow light of wavelength 577.1 nm had been shifted to green with a wavelength of 563.4 nm? Note: For speeds less than 0.03c, the equation below will lead to a value for the observed frequency accurate to approximately two significant digits.

1. A red photon has a wavelength of 660 nm. How fast must a star be moving toward the Earth for a red photon emitted by the star to change its color to an orange photon of wavelength 620 nm? You may, if you wish, express your answer either in m/s or in terms of the speed of light c (e.g., "0.021c"). [You'll need to do a little bit of algebra. Keep in mind that, by convention, the velocity...

Emission line spectra for various elements are shown in Table 1
and Table 2 shows the wavelengths for various colors. Remember, E =
h*c/?, where E is energy, h = 6.626*10-34 J*s, c =
3.00*108 m/s, ? is the wavelength, and 1 m =
109 nm.

If the plain wanted to leave the Earth, how fast would it need to fly? a) Given the fallowing equation, derive the formula for escape velocity. 1/2mv2(power) - kgmMe/Re) A black hole is not just science fiction, it is a case where the mass of a star collapses inward. The “Radius” of this hole is from the center, known as the singularity, and the very edge of the black hole. That edge is called the Event Horizon. This is where...
