Question: If an ultraviolet light source is moving towards us fast enough, this light could be blueshifted into the blue end of the visible spectrum. Question
If an ultraviolet light source is moving towards us fast enough, this light could be blueshifted into the blue end of the visible spectrum. Question 1 options: True False Question 2 (2 points) Listen Beams of information (electromagnetic radiation) that we receive from Earth-orbiting satellites whose orbits are perfect circles are never shifted by the Doppler effect. Question 2 options: True False Question 3 (2 points) Listen Belle Jin Waffles and Chris P. Critters decide to perform an experiment. From opposite sides of a dark and abandoned bowling alley, Belle runs towards Chris, who is shining a pure red light at Belle. They hope to see the Doppler effect for light, but are disappointed because they do not see it. What went wrong? Question 3 options: Belle and Chris were too close together for there to be a Doppler shift; this effect is only noticeable at great distances. Chris was not moving. The Doppler effect for light only occurs when the light source is moving towards the observer. They should do the experiment again, this time with Belle standing still and Chris running towards her. Nothing. There is a redshift, but it is so pronounced that it pushed the wavelength into the infrared, which cannot be seen by the eyes. Nothing. Belle can not run as fast as she needs to run for the shift in wavelength to produce any noticeable color change in the red light
