Energy Unit Conversions
Energy Unit Conversions :
Energy can be expressed many ways. Two relationships allow us to freely convert between energy, wavelength and frequency (see below). If we know any one of these three properties, we know the other two. For the budding scientist there are the two relationships that relate energy, frequency and wavelength. The first is c = vλ where c = the speed of light in vacuum (3.00 x 108m/s), v = frequency and λ is wavelength. The second is E = hv where E = energy, h is a special constant called Planck's constant (6.63 x 10-34J.s) and v is again frequency. The second equation tells us that frequency is proportional to energy. Combining the two, we find that frequency and energy are inversely proportional to wavelength
