The correct response is:
"Wavelength and energy have an indirect relationship, and when wavelength increases, energy decreases."
This is because energy (E) and wavelength (λ) are related through the equation \( E = \frac{hc}{\lambda} \), where \( h \) is Planck's constant and \( c \) is the speed of light. As the wavelength increases, the energy decreases, and vice versa.
