# Relation between frequency wavelength and speed of light

- In a dispersive medium, the phase speed itself depends upon the frequency of the wave, making the relationship between wavelength and frequency nonlinear. In the case of electromagnetic radiation—such as light—in free space, the phase speed is the speed of light, about 3×10 8 m/s.

For example, 10 waves of wavelength 10 meters will pass by a point in the same length of time it would take 1 wave of wavelength 100 meters. Since all forms of electromagnetic energy travel at the speed of light, the wavelength equals the speed of light divided by the frequency of oscillation (moving from crest to crest or trough to trough). There is a simple relation between the energy density in a cavity, , and the black body emissive power of a black body which simply comes from an analysis of how much radiation, traveling at the speed of light, will flow out of a hole in the cavity in one second. These massless particles travel at the speed of light (300,000 kilometers per second in a vacuum). Every photon is characterized by wavelength (the distance from the crest of one wave to the crest of the next wave), by frequency (the number of wave cycles that pass by in a given period, measured in Hertz, which stands for cycles per second), and by the energy it carries (measured in electron volts). Given that the speed of light in a vacuum is {eq}c = 3.00 \times 10^{8}\ \rm{m/s} {/eq} and knowing that the relationship between this speed, wavelength ({eq}\lambda {/eq}) and frequency ({eq}f ... Describe the relationship between wavelength, frequency, and speed of light Wavelength and frequency travel at the speed of light and the speed of light determines both wavelength and frequency. The inverse relationship between wavelength and frequency means that as wavelengths increase, the frequency decreases.

That means that the wave has moved by one wavelength. Since speed is distance traveled / time spent, and a wave moves a distance of one wavelength in a time of one period, its speed must be: speed = distance / time = wavelength / period v = λ / p We more often use frequency = 1 / period. Then: speed = wavelength x frequency In general, ##f=c_0 n/\lambda##, where f is frequency, ##c_0## is the speed of light in vacuum and ##\lambda## is the wavelength. The index of refraction, n, is typically a function of frequency itself, so that the relation between frequency and wavelength becomes non-linear. This is called dispersion. Yellow has longer wavelength and lower frequency c. Yellow light and violet light are both in the visible range of the electromagnetic spectrum. Identify two other similarities between yellow light and violet light. Yellow light and Violet light both travel at the speed of light, they also travel through a vacuum. The frequency or wavelength of the wave do not affect the speed that the wave travels. Thus, on a given rope, the wavelength and frequency are inversely proportional. Because all electromagnetic radiation moves at the same speed (speed of light) wavelength and frequency are related. If the wavelength is long, there will be fewer cycles passing a given point per second, thus the frequency will be low; If the wavelength is short, there will be more cycles passing a given point per second, and the frequency will be high; Thus, there is an inverse relationship between wavelength and frequency

Wavelength, frequency, and amplitude The wavelength and frequency of a wave are related by the speed of light, the speed at which all electromagnetic radiation travels in a vacuum. The speed of light in a vacuum, 2.998 108 m/s, is λ ν = c (or ν = c/λ) - the product of frequency and wavelength is the speed of light. Alternatively, the frequency of a wave is inversely proportional to the velocity. E = hν = hc/λ , where h is the Planck constant, 6.626 x 10-34 - The energy of the radiation is equal to the Plank constant multiplied by the frequency of the radiation. Longer wavelength = bigger lambda; since speed of light through the medium v = (lambda)(f), bigger lambda = bigger v = faster speed through medium. So, for our light traveling through glass example, if our light has a longer wavelength, it's going to have a bigger v1, which means it's going to have a smaller n1. 1-32 COMPARISON OF LIGHT WAVES WITH SOUND WAVES There are two main differences between sound waves and light waves.
