Which involves reflection of light waves? a. a full moon shows sunlight bouncing off the moon's surface and traveling toward earth. b. ultraviolet waves of energy are taken in by sunburned skin.. c. a black car will heat up more in the sun than a lighter colored car.

50.)the diagram below represents the wave fronts produced by a point source moving to the right in a uniformmedium. observers are located at points a and b.compared to the wave frequency and wavelength observed at point a, the wave observed at point b has a(1) higher frequency and a shorter wavelength(2) higher frequency and a longer wavelength(3) lower frequency and a shorter wavelength(4) lower frequency and a longer wavelength
