The SI unit for energy is a joule. In physics it is defined as the property of objects or fields, which allows it to perform work on other objects, for example to cause motion. The above inverse relationship means that light consisting of high energy photons (such as "blue" light) has a short wavelength. Light from 400â700 nanometers (nm) is called visible light, or the visible spectrum because humans can see it.Light outside of this range may be visible to other organisms but cannot be perceived by the human eye. Energy is a notion central to physics, chemistry, physiology, and life itself. Converting joules to hertz and wavelengths? J = Nm . The human eye sees color over wavelengths ranging roughly from 400 nanometers (violet) to 700 nanometers (red). Light consisting of low energy photons (such as "red" light) has a long wavelength.
