Our experts can answer your tough homework and study questions. the Greek letter lambda λ is the symbol for wavelength. (B) A wave with a short wavelength (top) has a high frequency because more waves pass a given point in a certain amount of time. Radio waves travel at the speed of light in a vacuum. Ans: Given, Frequency of light = $$6.24\times … v= lamda * frequency. The frequency is 99.0 MHz of a radio station!? Calculate the energy of the photon using the wavelength and frequency along with the Planck constant (6.6261 × 10 −34 J*s) and speed of light. If an R.F. The amplitude is the height of the wave. c = Speed of Light (299,792,458 m/s) f = Frequency (MHz) Advertisement. From the graphic above, the only means of finding the frequency is to use the wave equation (speed=frequency • wavelength) and knowledge of the speed and wavelength. You can also calculate how long it takes sound to travel a given distance or how far sound will travel within a given time span. Wave velocity (m/s) =Wavelength (m) * Frequency (Hz) Example calculation. If you're seeing this message, it means we're having trouble loading external resources on … e.g. can be found using the equation: λ = 17.0 m. The wavelength of the sound is 17 meters.

By comparison, a typical carrier for FM is 100 MHz, with a wavelength of 3 m, and could use an antenna only 80 cm long. You can also calculate how long it takes sound to travel a given distance or how far sound will travel within a given time span. The number of cycles completed in one second is called the frequency. Just plug all 4 pieces of information into the formula above. First, select the speed of sound. If a string of a violin or a harp vibrates back and forth, it is compressing and expanding the surrounding air, thus producing a sound.
