Extrasolar Planets. In the not-too-distant future, it should be possible to detect the presence of planets moving around other stars by measuring the Doppler shift in the infrared light they emit. If a planet is going around its star at 50 km/h while emitting infrared light of frequency 3.330 x 1014 Hz, what frequency light will be received from this planet when it is moving directly away from us?

Question
Extrasolar Planets. In the not-too-distant future, it should be possible to detect the presence of
planets moving around other stars by measuring the Doppler shift in the infrared light they emit. If a planet
is going around its star at 50 km/h while emitting infrared light of frequency 3.330 x 1014 Hz, what
frequency light will be received from this planet when it is moving directly away from us? (Note: Infrared
light is light having wavelengths longer than those of visible light.)
