What The relation between frequency and wavelength is the comparable for easy as with the different wave (sound, water). The wavelength of light … List the colors of light in the visible spectrum in order of increasing frequencies. But the wavelength of visible light ranges from 400 to 700 nm. wave's frequency multiplied by its wavelength equals the speed of light. Because all light waves move through a vacuum at the same speed, the number of wave crests passing by a given point in one second depends on the wavelength. The speed of light is equal to frequency times wavelength (c=v*lambda). Thus the frequency of the first wave is greater than that of the second wave. Since wavelength is inversely proportional to the frequency, we can understand that, longer the wavelength of the light, lower is the frequency. The energy of a single photon that has the wavelength λ is given by: f = c / λ and λ = c / f For instance, the “middle C” note is a sound wave with a frequency of 261.63 Hz. is electromagnetic radiation? How are frequency and wavelength of light related?
