How have the competing explanations' experiments on atoms affected the development of the atomic model? A: The atomic model better represents the actual functioning of an atom.

B: The atomic model has become much simpler than it used to be.

C: The atomic model now involves fewer subatomic particles.

D: The atomic model has become less strong over time.

Ultraviolet radiation is dangerous because it has a high enough energy to damage skin cells. what is the best explanation of the relationship between wavelength and wave energy? a) wave energy is related only to frequency, not wavelength. b) longer wavelengths have lower frequencies but higher energy. c) the shorter the wavelength, the lower the frequency and the higher the energy. d) the shorter the wavelength, the higher the frequency and the higher the energy.
