Do an ultraviolet wave has more energy than a microwave because it has a shorter wavelength and a higher frequency?

Answer 1

Yes, that's correct! Ultraviolet (UV) waves have more energy than microwaves because they have shorter wavelengths and higher frequencies.

In electromagnetic radiation, energy is directly related to frequency and inversely related to wavelength. The relationship is described by the equation:

\[ E = h \cdot f \]

where \( E \) is energy, \( h \) is Planck's constant, and \( f \) is the frequency of the wave.

Since UV waves have higher frequencies than microwave waves, they correspond to higher energy levels. Similarly, the shorter wavelength of UV waves compared to microwaves aligns with this relationship, indicating that UV radiation carries more energy per photon than microwave radiation.
