The longest one does.
If you're talking about visible light, then it's the last color you can see
on the red end.
If you're talking about the electromagnetic spectrum in general, then
there's no such thing as the "lowest" frequency.
-- longest wavelength -- lowest frequency
The formula for wavelength λ = v/f where v is the velocity f is the frequency of the wave and λ (lambda) is the symbol for wavelength Wavelength formulaC=λf or λ=C/f
In the spectrum of electromagnetic radiation the wave property that changes is the frequency. So for example xrays have higher frequency then blue light which has higher frequency then red light which has higher frequency then radio waves etc.
When the frequency of a wave passing through a uniform medium increases, its wavelength decreases. This is because the speed of the wave remains constant in the medium, so an increase in frequency results in shorter wavelengths to maintain the same wave speed.
Assuming that the air is dry and room temperature is 20 degrees celcius then the spped of sound is 343m/s. The frequency of the sound will be 185.4054Hz
-- longest wavelength -- lowest frequency
the lowest frequency Lester was here
Violet has the shortest wavelength and highest frequency among visible light colors, whereas red has the longest wavelength and lowest frequency.
Wave 4 has the lowest frequency as it has the longest wavelength among the four waves. Frequency and wavelength are inversely proportional, so the longer the wavelength, the lower the frequency.
The energy of EM radiation depends on its frequency, and the lowest frequency corresponds to the lowest energy. Radio waves are at the low end of the energy and frequency spectrum.
Radio waves have the longest wavelength and lowest frequency among electromagnetic waves. They are used for communication, broadcasting, and radar systems.
The part of the electromagnetic spectrum with the lowest frequency and longest wavelength is radio waves. They are used for communication, broadcasting, and radar.
Provided you compare waves that all have the same speed, the longest wave has the lowest frequency.
The longest visible wavelength of light appears red. "Longest wavelength" is equivalent to 'lowest frequency'.
Electromagnetic waves
Radio waves have the longest wavelength and the lowest frequency among all types of electromagnetic waves. They are used in communication and are emitted by sources like radio stations and cell phones.
The type of wave that has the longest wavelength and lowest frequency is a radio wave. These waves are used for communication and broadcasting due to their ability to travel long distances.
