The correct answer is:
A. The energy increases.
As you move from red to violet in the visible light spectrum, the energy of the light increases. This is because the energy of light is directly related to its frequency and inversely related to its wavelength. Therefore, as the frequency increases (from red to violet), the energy also increases.
To clarify the other options:
B. The speed of light remains constant in a vacuum for all colors, so this is incorrect.
C. The wavelength decreases as you move from red to violet, not increases.
D. The frequency increases as you move from red to violet, not decreases.
