Other uncategorized cookies are those that are being analyzed and have not been classified into a category as yet. As the wavelength of light increases the frequency decreases. It also does not affect wave speed. So, if you have a bigger energy jump, you will absorb light with a higher frequency - which is the same as saying that you will absorb light with a lower wavelength. The speed of the wave will increase. So the longer the wavelengths and lower the frequency results in lower energy. Part II: 1. Thus as frequency increases (with a corresponding decrease in wavelength), the photon energy increases and visa versa.
