Question

study the images above. choose all three of the statements below that are true regarding wave energy. a letter j identifies the wavelength of the wave. b if letter j was longer, the wave would have more energy. c letter g represents the frequency of the wave. d if letter g was longer, the wave would have more energy. e

Explanation:

1. Wavelength is the distance between two consecutive crests or troughs. If J represents this distance, A can be correct.
2. Energy of a wave is inversely - proportional to wavelength. Shorter wavelength means more energy, so B is incorrect.
3. Frequency is the number of waves passing a point per unit time. If G represents this count, C can be correct.
4. Longer G (assuming it represents frequency) means higher frequency and more energy as $E = hf$ (where $E$ is energy, $h$ is Planck's constant, and $f$ is frequency), so D can be correct.
5. Gamma - rays, not radio - waves, have the most energy in the electromagnetic spectrum, so E is incorrect.

Answer:

A. Letter J identifies the wavelength of the wave.
C. Letter G represents the frequency of the wave.
D. If letter G was longer, the wave would have more energy.
