What Is Wavelength?


Quick Answer

A wavelength is the distance between two peaks on two different waves that are traveling in space. Waves are electromagnetic radiation that are comprised of either light or heat. Both light and heat waves travel through space to transfer energy.

Full Answer

Wavelengths are important concepts in physics and chemistry. To calculate the analytical value of a wavelength, students must graph the waves. The wavelength then can be determined by looking at two similar waves with the same phases. These waves must not cross and must be adjacent to each other. Then, students can measure the distance between the two highest peaks to determine the wavelength. In physics, wavelength is directly related to the frequency of the wave.
