it depends on the wavelength

========================

The frequency of any electromagnetic signal ... in fact the frequency of any wave ... is

(speed of the wave)/(wavelength) .

For light, that's 300,000,000/(wavelength in meters) , and the answer is in Hertz.

The lowest frequency of light that your eye can detect is around 7.5 x 1014 Hz.

That's 750,000,000,000,000 Hz ... 750,000 Gigahertz ! (for 400 nm wavelength)

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.


Which has a lower frequency yellow light or blue light?

Blue light has a higher frequency compared to yellow light.


How does frequency affect light?

The frequency of light determines its color – higher frequency light appears bluer, while lower frequency light appears redder. In addition, the frequency of light affects its energy – higher frequency light carries more energy per photon. This is why higher frequency ultraviolet light is more harmful to living organisms than lower frequency visible light.


When the frequency of light matches the natural frequency of molecules in a material light is?

When the frequency of light matches the natural frequency of molecules in a material, light is absorbed by the material. This phenomenon is known as resonance absorption.


How does the wavelength of light compare to it's frequency?

The wavelength of light is inversely proportional to its frequency. This means that light with a shorter wavelength will have a higher frequency, and light with a longer wavelength will have a lower frequency. In other words, as the wavelength decreases, the frequency increases.


Is the frequency of blue light higher or lower than violet light?

Blue light has a lower frequency than violet light. Violet light has the highest frequency in the visible spectrum, while blue light has a slightly lower frequency than violet light but higher than green light.


How could you find the wavelength of light if you knew its speed and frequency?

You can use the equation: wavelength = speed of light / frequency. Given the speed of light (3.00 x 10^8 m/s) and the frequency of the light source, divide the speed of light by the frequency to determine the wavelength of the light.


Is the frequency of purple light higher or lower than yellow light?

The frequency of purple light is higher than yellow light. Purple light has a shorter wavelength and higher frequency compared to yellow light which has a longer wavelength and lower frequency.


What happenes to the frequency of light when its wavelength increases or decreases?

When the wavelength of light increases, the frequency decreases. Conversely, when the wavelength decreases, the frequency increases. This relationship is described by the equation: frequency = speed of light / wavelength.


Why is frequency of red greater than violet?

The frequency of red light is lower than the frequency of violet light. This is because red light has a longer wavelength, which corresponds to a lower frequency. This difference in frequency is what causes red light to be more common than violet light in natural light sources.


What is the formula for converting frequency of light into wavelength?

wavelength = c/frequency of light where c is the speed of light.


Does red light have a higher frequency than green light?

No, red light is lower frequency than green light.
