How To Find The Frequency Of A Wave Calculator

Frequency, speed and wavelength calculators

Speed, Frequency and Wavelengh Calculator

This page contains a frequency calculator, as well as calculators with the equation rearranged to make speed and wavelength the subject. The formulas are shown together with other useful information and examples to endeavor. Unit converters (feet to metres then on) can be establish here (opens in a new tab). Note that when because electromagnetic radiation, such every bit light, the quantity speed is usually denoted by the letter c, just otherwise the letter v (continuing for velocity) is usually used. Nosotros will apply v on this page in all cases, which is measured in metres per second (k/south).

Frequency (f)

The equation for frequency is given on the right. Case : A particular AM radio station uses a wavelength of 250 metres. What frequency practice we need to tune our receiver to in order to hear the broadcast? Radio waves travel at the speed of calorie-free, so in this case 5 is equal to 299,792,458 metres per second (m/south). Putting these figures (without commas) into the calculator above shows that we need to tune the radio receiver to 1199.2 kHz (or 1.1992 MHz), which is around the middle of the medium moving ridge (MW) band.

The equation for frequency is: Where: f = frequency (s-1, or Hz) v = velocity (m/s, ms-1) λ = wavelength (m)

Wavelength (λ)

The equation for wavelength is given above right. Example: Microwave ovens use electromagnetic radiation with a frequency close to ii.45 GHz to heat up food. What is the wavelength of the radiation? Radio waves travel at the speed of calorie-free, so in this instance five is equal to 299,792,458 metres per 2d (m/s), and 2.45 GHz is 2,450,000,000 Hz, so that's the frequency. Putting these figures (without commas) into the calculator above shows that the wavelength is 0.122 metres, or 12.2 centimetres.

The equation for wavelength is: Where: λ = wavelength (m) v = velocity (k/s, ms -i ) f = frequency (southward -ane , or Hz)

Mutual metric prefixes kilo (thou): 1,000 (thousand) mega (Grand): 1,000,000 (million) giga (M): i,000,000,000 (billion) Other metric prefixes are listed hither .

Velocity (5)

The equation for velocity is given in a higher place right. Case: Sound travels in waves and does then at a detail speed depending on what information technology is travelling through, such as air, brick or h2o. To observe the speed of sound in air we tin notation that the musical note A above eye C has a frequency of 440 Hz and a wavelength of 0.773 metres. Putting these figures into the figurer in a higher place shows that the speed of sound in air is close to 340.1 meters per second.

The equation for velocity is: Where: v = velocity (m/s, ms -1 ) f = frequency (due south -1 , or Hz) λ = wavelength (yard)
