Assuming you mean visible light, that would be red light.

What color had the lowest frequency?

Violet has the shortest wavelength and highest frequency among visible light colors, whereas red has the longest wavelength and lowest frequency.


Which light has the longest wavelength and the shortest frequency?

The longest visible wavelength of light appears red. "Longest wavelength" is equivalent to 'lowest frequency'.


Photons with lowest energy have the?

-- longest wavelength -- lowest frequency


What did you observe with the wavelength and frequency of the different colors?

Shorter wavelengths correspond to higher frequencies, so violet light has a shorter wavelength and higher frequency than red light. In the visible spectrum, red light has the longest wavelength and lowest frequency, while violet light has the shortest wavelength and highest frequency.


How would the wavelength and frequency of a red light compare to the wavelengths and frequencies of green and violet lights?

-- Red light has the lowest frequency of those three. -- Green light has lower frequency than violet light has. -- The wavelength of all light is inversely proportional to its frequency.


Which type of visible light has the longest wavelength?

The longest wavelength / lowest frequency visible light is the red end of the spectrum. The shortest wavelength / highest frequency visible light is the violet end of the spectrum.


What is the lowest frequency blue or red?

Red has a lower frequency than blue. Blue light has a higher frequency and shorter wavelength compared to red light.

What is the relationship of color of light and frequency?

Each colour of visible light has a different frequency. Red has the lowest frequency, meaning it has a long wavelength. Purple has the highest frequency and has a very short wavelength. The order is: red, orange, yellow, green, blue, purple. I hope this helps you!


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.


Which color of the visible light portion the the electromagnetic spectrum has the lowest frequency and the least energy?

The last color you can see at the red end has the lowest frequency,longest wavelength, least energy per photon.The last color you can see at the violet end has the highest frequency,shortest wavelength, most energy per photon.


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.
