Question

As the frequency (v) of an electromagnetic wave increases. Its speed must increases. Its amplitude must increases. Its wavelength must increases. Its energy must increases. Complete this sentence: Atoms emit visible and ultraviolet light as electrons jump from lower energy levels to higher levels. As the atoms condense from a gas to a liquid as electrons jump from higher energy levels to lower levels. as they are heated and the solid melts to from a liquid. As the electrons move about the atom within an orbit.

Explanation / Answer

1)   Answer B
We knowv E = hf and E = hc/wavelength. since if E = hf, increasing f means more energy, which is represented in the wave having a larger amplitude.
2)   Answer C As electrons jump from higher energy levels to lower levels

they are moving to a lower energy level and the excess energy is released as light energy
