The frequency of a light wave with a wavelength of 680nm is approximately 440 THz (terahertz). This can be calculated using the formula: speed of light (c) = wavelength (λ) × frequency (f), where c is approximately 3 × 10^8 m/s.

What happens to the wavelength when the frequency of a light wave increases?

When the frequency of a light wave increases, the wavelength decreases. This is because wavelength and frequency are inversely proportional in a wave, meaning as one increases, the other decreases.


What is the wave length of a frequency of X?

The wavelength of a wave with frequency X can be calculated using the formula: wavelength = speed of light / frequency.


What can you do to decrease the value of wavelength?

To decrease the value of wavelength, you can increase the frequency of the wave. This is because the wavelength and frequency of a wave are inversely related according to the wave equation: wavelength = speed of light / frequency. So, by increasing the frequency, you will effectively decrease the wavelength.


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 decreases as the frequency of a sound wave increases?

Wavelength.


How are the frequency and the wavelength of a light wave related?

How are frequency and wavelength of electomagnetic waves realted?

Frequency and wavelength of electromagnetic waves are inversely proportional. This means that as the frequency of a wave increases, its wavelength decreases, and vice versa. This relationship is described by the equation: wavelength = speed of light / frequency.


Examples of the equation velocity equals frequency wavelength?

Any wave. Of you have a wave (light, water etc.), it will have a frequency and a wavelength. Multiply these and you get the speed at which the wave is moving.


What is the formula for finding the frequency of a wave?

The wavelength of a wave is calculated using the formula: Wavelength = speed of the wave divided by the frequency of the wave. For radio waves and other wireless signals as well as the speed a signal travels along a wire, the speed of the wave is approximately 299,792,458 meters per second (the speed of light).


What is the frequency of a violet light wave with a wavelength of 410.17?

The frequency of a violet light wave with a wavelength of 410.17 nm can be calculated using the equation: speed of light = frequency x wavelength. Given that the speed of light is approximately 3 x 10^8 m/s, you can solve for the frequency using the wavelength provided.


What is wave length times frequency?

The product of wavelength and frequency is the speed of the wave, which is a constant value for a specific medium, such as the speed of light in a vacuum. The equation that relates wavelength, frequency, and speed is: speed = wavelength * frequency.


How are wavelength frequency and energy are related?

Energy of light photons is related to frequency as Energy = h(Planck's constant)* frequency Frequency = velocity of wave / wavelength So energy = h * velocity of the wave / wavelength
