Shorter vs Longer Wavelength

Postby Enrico Cortes » Sun Oct 04, 2015 7:33 pm

Why is a shorter wavelength more able to eject an electron than a longer wavelength? What specific property does the shorter wavelength have than the longer one?

Shorter wavelengths of light have more energy than longer wavelengths of light do.

It mainly has to do with their inverse relationship with frequency. Shorter wavelengths coincide with higher frequencies, which are what directly result in increased energy.

The shorter the wavelength the higher the frequency thus it carries more energy. In this formula you can see how they are inverse: . Since c (speed of light) is constant, wavelength and frequency must balance out inversely to make sure its value stays the same. This then translates to the following equation: = . If frequency () increases, energy (E) also increases. However, for frequency to be large, wavelength must be small as stated in the previous formula.

The smaller the wavelength, the larger the energy. The larger the wavelength, the smaller the energy.

Adding onto this, there's something I've been confused about. Is there more energy because a greater amount of photons is able to bombard the electron at a given instance because of the higher frequency or because each individual photon just has more energy?

Shorter wavelengths have higher frequencies. E= planks constant times frequency. Higher frequency will give you a higher energy.
