Human beings can hear sound waves in the frequency range of 20 Hz - 20 kHz. So, the required shortest wavelength that human beings can hear is 20 Hz.
At a speed of sound of 340 meters/sec, that frequency corresponds to a wavelength of
(340/20) = 17 meters, in air.
Maximum around 20 000 Hz.

The longest visible wavelength of light appears red. "Longest wavelength" is equivalent to 'lowest frequency'.
The electromagnetic waves with the longest wavelength are called radio waves.
The color red has the longest wavelength of all the colors in the light spectrum.
The colour of visible light with the longest wavelength is red (approximately 700 nanometres).
radio waves
Yes, that's correct.
There is no longest wavelength for photons. It can be arbitrarily long.
"radio waves" have longest wavelength..
The longest visible wavelength of light appears red. "Longest wavelength" is equivalent to 'lowest frequency'.
Red light has the longest wavelength.
The longest wavelength of light that a human eye can perceive depends on the individual, but is generally in the neighborhood of 750 nanometers (7.5 x 10-7 m). Light with that wavelength is perceived by the retina/brain system as colored red.
Red is the longest wavelength of visible light
Red is the longest wavelength of visible light
-- longest wavelength -- lowest frequency
The electromagnetic waves with the longest wavelength are called radio waves.
The color red has the longest wavelength of any color.
The color red has the longest wavelength of all the colors in the light spectrum.
