Best Answer

to find the frequency of a light wave you need to know its wavelength. The frequency is equal to the speed of light (3x10^8 m/s) divided by the wavelength in metres. Alternatively, if you were given the energy of each photon of light in joules you could just divide the energy by plancks constant (6.63x10^-34) to leave you with the frequency in Hz.

What is an example of frequency?

Frequency can be found in sound, light, and line current. An example of frequency is, the frequency wave of light will determine what color the light is.


What properties of a light wave determine its color?

Frequency or wave length.The relation between frequency f and wave length lof a light waveis given by; f = c/l, where c is light's speed.


The wavelength of a light wave can be used to measure?

The wavelength of a light wave can be used to measure the frequency of the wave, as well as its energy. Additionally, it is used to determine the color of the light based on the visible spectrum.


What equations tell us how fast a wave travels?

The speed of a wave can be determined by the equation: speed = frequency x wavelength. This equation relates the speed of a wave to its frequency and wavelength. Additionally, the wave equation, c = λf, where c is the speed of light, λ is the wavelength, and f is the frequency, can be used to determine the speed of electromagnetic waves in a vacuum.


Which wave components determine a waves energy?

Amplitude times frequency.


How do you calculate the wavelength of frequency?

You can calculate the wavelength of a wave using the formula λ = c / f, where λ represents the wavelength, c is the speed of light (3 x 10^8 m/s), and f is the frequency of the wave in Hertz. Simply divide the speed of light by the frequency to determine the wavelength.


What determine the color of a light wave?

Its wavelength (or frequency).


What is the energy of an electromagnetic wave that has a wavelength of 9.0 10-6 m?

The energy of an electromagnetic wave is proportional to its frequency. You can calculate the frequency using the formula: frequency = speed of light / wavelength. Once you have the frequency, you can determine the energy using the formula: energy = Planck's constant * frequency.


How can you determine a speed of a wave?

by multiplying its frequency


In a wave of light why are frequency and wavelegnth important?

Frequency and wavelength in a light wave are important because they determine the energy and properties of the light. The frequency determines the color of the light, with higher frequencies corresponding to bluer colors and lower frequencies to redder colors. The wavelength affects how the light interacts with different materials and influences properties like diffraction and interference.


What determines the frequency of an electromagnetic wave?

The frequency of an electromagnetic wave is determined by the speed of light divided by the wavelength of the wave. This relationship is defined by the equation: frequency = speed of light / wavelength.


What is the correlation between the length of a light wave and it's frequency?

The correlation between the length of a light wave and its frequency is inverse: as the length of the light wave increases, its frequency decreases, and vice versa. This relationship is described by the formula: speed of light = wavelength x frequency.
