Electromagnetic waves always travel at the same speed (299,792 km per second). This is one of their defining characteristics. In the electromagnetic spectrum there are many different types of waves with varying frequencies and wavelengths. They are all related by one important equation: Any electromagnetic wave's frequency multiplied by its wavelength equals the speed of light.visible light represents a narrow group of wavelengths between about 380 nm and 730 nm.  Our eyes interpret these wavelengths as different colors.  If only a single wavelength or limited range of wavelengths are present and enter our eyes, they are interpreted as a certain color.  If a single wavelength is present we say that we have monochromatic light.  If all wavelengths of visible light are present, our eyes interpret this as white light.  If no wavelengths in the visible range are present, we interpret this as dark.

The energy of 1 photon of light is determined by planck's equation.
$E_{photon}=\dfrac{h*c}{\lambda}=h*\nu$

The frequency $(\nu)$ is the number of oscillations per second, while the wavelength $(\lambda)$ is the distance for the wave to reach the same height again. "h" is planck's constant 6.626*10$^{-34}$.
