Infrared radiation has wavelengths between 700 nm and 1 millimeter (mm). In infrared the detected radiation is turned into an image on a screen, hotter objects showing up brighter. Radio waves have the longest wavelengths in the electromagnetic spectrum.
Read moreWhat has a long wavelength and low frequency?
The frequency of a wave is inversely proportional to its wavelength. That means that waves with a high frequency have a short wavelength, while waves with a low frequency have a longer wavelength. Light waves have very, very short wavelengths.
Read moreWhat type of wave has the longest wavelength and the lowest frequency?
Radio Waves — The waves in the electromagnetic spectrum that have the longest wavelengths and lowest frequency are called radio waves. Radio waves are used to transmit information from the antenna of a broadcasting station to the antenna of your radio or TV.

Assuming the speed of sound in air is 345 m/s, determine the wavelength of the sound corresponding to the note of middle C. Let λ = wavelength. Use v = f • λ where v = 345 m/s and f = 256 Hz. Rearrange the equation to the form of λ = v / f. … The Speed of Sound. a. one-ninthb. one-thirdc. the same asd. three times larger thanThe Speed of Sound – The Physics Classroom www.physicsclassroom.com › class › sound › Lesson-2 › The-Speed-of-So…
Read moreWhat is frequency of sound in physics?
The frequency of a sound wave not only refers to the number of back-and-forth vibrations of the particles per unit of time , but also refers to the number of compressions or rarefactions that pass a given point per unit of time.
Read moreHow do you find the frequency of sound?
To calculate the frequency of a wave, divide the velocity of the wave by the wavelength . Write your answer in Hertz, or Hz, which is the unit for frequency.
