An observer is moving in space toward a distant star at 110 km/s while the star is moving toward the observer at 230 km/s; the relative velocity being 340 km/s of approach. What relative change in frequency of the light from the star as seen by the observer? (The speed of light in space is 3.00 × 105 km/s).

Light radiates from a distant star that is moving towards Earth. In the Earth's frame of reference the light has a wavelength of 400 nm. If the star is moving with a speed of 0.41 c, what wavelength, in nm, will be seen by an observer in the star's frame. Calculated your answer to two decimal places.

a planet in an elliptical orbit around a distant star. a periastron (the point closest approach to the star), the planet is rp=4.20 x 10^8km from the star and is moving with the speed of vp=18.5km/s. when the planet is at apastron (the point of greatest distance from the star) it is ra=9,30x10^8 km from the star. how fast is the planet moving at apastron? va=? km/s

An astronomer observed electromagnetic waves emitted by oxygen atoms in a distant galaxy moving toward Earth at a speed of 2.467 times 10^7 m/s. In the laboratory on Earth, oxygen atoms emit waves that have a frequency of 5.841 times 10^14 Hz. At what frequency does the astronomer observe the light emitted by oxygen atoms from the distant galaxy? A certain metal has a work function for photoelectric emission of phi delta = 3.50 eV. What is the threshold frequency...
