Why does the Doppler effect lead to a shift in the wavelength of the light emitted by a star, but to a broadening of emitted light in a gas? Check all that apply. The wavelength of a star is shifted because all the photon emitters are moving in the same direction with respect to the observer. The wavelength of a star is shifted because all the photon emitters are moving randomly and with equal probability in all directions with respect to the observer. Emitted light in a gas is broadened because the atoms move randomly and with equal probability in all directions with respect to the observer. Emitted light in a gas is broadened because the atoms move in opposite directions with respect to the observer. Submit Previous Answers Request Answer X Incorrect: Try Again: 4 attempts remaining

Traffic signals are often now made of LEDs (light-emitting diodes). Amber and green ones are pictured here. (a) The light from an amber signal has a wave-length of 595 nm, and that from a green signal has a wavelength of 500 nm. Which has the higher frequency? (b) Calculate the frequency of amber light.
The Doppler effect is one of the sources of the line broadening in atomic absorption spectroscopy. Atoms moving toward the light source encounter higher-frequency radiation than atoms moving away from the source. The difference in wavelength experienced by an atom moving at speed v (compared to one atrest) is / = v/c , where c is the velocity of light. Estimate the line width (in nanometers) of the lithiumline at 670.776(6707.76 Å) when the absorbing atoms are at a temperature of (a) 2000 K and (b) 3120 K.The average speed of an atom is given by v=8kT/m , where k is Boltzmann’s constant, Tis the absolute temperature, and m is its mass.
Photons of infrared radiation are responsible for much of the warmth we feel when holding our hands before a fire. These photons will also warm other objects.
