• T. The wavelength of light emitted from a receding object appears to increase, that is, it appears to be redder.
• An approaching object will appear bluer because of the Doppler shift.
IQ• The speed of light, usually denoted by ‘c,’
is constant. The value of this constant velocity is very nearly 3 X 105 km/s. This means that the speed of light derived from a galaxy moving away from us at 1000 km/s will be slower by:
• A. 0%• B. (103 km/s/ 3 X 105 km/s) * 100 = 3.33%• C. 10%• D. 52.5%
