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.
Gamma radiation has the smallest wavelength.
The lowest visible frequency for you is the frequency of the last color you can see
on the red end of the rainbow. It's not exactly the same for everybody's eyes.
The red end has.
red
-- 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
If you change sound's frequency and hold the velocity constant, the sound's wavelength also changes. If you change sound's frequency and keep the wavelength constant, then velocity also changes.
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.
The wavelength gets longer.
-- longest wavelength -- lowest frequency
the lowest frequency Lester was here
The longest visible wavelength of light appears red. "Longest wavelength" is equivalent to 'lowest 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.
Provided you compare waves that all have the same speed, the longest wave has the lowest frequency.
Radio waves
Electromagnetic waves
No. In the visible portion of the electromagnetic spectrum, the waves at the red end have the longest wavelength (lowest frequency), and those at the violet end have the shortest wavelength (highest frequency).
I think it is radio waves!
half the wavelength of the lowest frequency
Each color has a different frequency and wavelength; with red having the longest wavelength and lowest frequency of all the visible colors & violet having the shortest wavelength and highest frequency of the colors humans can see.
There are many types of waves, but the main ones are: radio waves, microwaves, infrared waves, visible light waves, ultraviolet waves, x-rays, and gamma rays. Radio waves have the longest wavelength and lowest frequency. Gamma rays have the shortest wavelength and highest frequency.
