What happens to frequency and energy as the wavelength decreases?

As the wavelength of a wave decreases, the frequency increases, and consequently, the energy associated with that wave also increases. This relationship is grounded in the fundamental principles of wave physics, where frequency and wavelength are inversely related through the equation:

[ \text{Speed of Light} = \text{Wavelength} \times \text{Frequency} ]

When the wavelength becomes shorter, the frequency must increase to maintain the constant speed of the wave (in the case of electromagnetic waves like light, for example). Since energy is directly proportional to frequency (illustrated by the equation ( E = h \cdot f ), where ( E ) is energy, ( h ) is Planck’s constant, and ( f ) is frequency), an increase in frequency results in an increase in energy.

Therefore, as the wavelength decreases, both the frequency and the energy increase, confirming that the correct answer is indeed that there is a higher frequency and energy.
