Wavelength

Postby ATingin_3I » Sat Oct 12, 2019 3:31 pm

why is it that when we decrease the wavelength, the energy and frequency increases?

Wavelength and frequency are inversely related. Therefore, with a shorter wavelength, there would be a higher frequency, and the wave completes more cycles per second (in Hz.) On the other hand, frequency and energy are directly related. As frequency increases, so will energy, as modeled by the equation E=hv.

since the speed of light is always the same c = 3.0*10^8 and c=wavelength * frequency, as wavelength decreases frequency must increase and the same idea applies to energy since frequency and energy are directly related

I completely agree with what the previous person said. However, I want to add that wavelength and frequency are inversely related because c= λ ν. Since c is a constant, wavelength increases when frequency decreases and vice versa.

When waves are longer, they travel slower so they have less energy. Shorter waves travel faster, and, therefore, have much more energy.
