The correct answer is
<span>B) UV waves are higher frequency and carry more energy.
In fact, UV waves have higher frequency than visible light. For comparison, visible light has frequency in the range 430-770 THz (</span>
)<span>, while ultraviolets (UV) have frequency higher than these values (at the order of 1 PHz, </span>
).
The energy of electromagnetic radiation is proportional to its frequency, according to the equation
where h is the Planck constant and f is the frequency. We see that the higher the frequency, the greater the energy, so UV waves carry more energy than visible light.
