Final answer:

Two rays of light with the same color will have the same frequency, as color is determined by frequency. Brightness is related to wave amplitude or photon count, not frequency. The properties of light concerning energy, wavelength, and frequency are inversely proportional, affecting one another according to the principles of the electromagnetic spectrum.

Step-by-step explanation:

When two rays of light have the same color but one is brighter than the other, they have the same frequency because color is determined by frequency. Brightness does not affect the frequency or color of light; it is related to the amplitude of the light waves or the number of photons being emitted. Therefore, in your statement, both rays would have the same frequency.

For the properties of light:

  1. If "light C" has a shorter wavelength than "light D", then "light C" has a larger energy than "light D" because energy is inversely proportional to wavelength.
  2. If "light E" has a higher frequency than "light F", then "light E" has a shorter wavelength than "light F" since wavelength is inversely proportional to frequency.
  3. If "light G" has a higher frequency than "light H", then "light G" has a larger energy than "light H" because energy increases with frequency.
  4. If "light J" has larger energy than "light K", then "light J" has a shorter wavelength than "light K" because higher energy implies a shorter wavelength.

Regarding the order of colors by wavelength and frequency: red light has the longest wavelength and the lowest frequency, while blue light has the shortest wavelength and the highest frequency. Therefore, the order from shortest wavelength to longest wavelength is blue, yellow, red; and from lowest frequency to highest frequency is red, yellow, blue.
