The period is ' 1 ' divided by the frequency. (The reciprocal of the frequency.)
The question tells us the frequency . . . "3 per second".
So the period is 1/3rd of a second .
Having the frequency, the wavelength doesn't give us any more information (except that
now we know the speed of the wave, but that's irrelevant at the moment.)
The first has half the wavelength of the second
Period = 1 / (frequency) = 1 / 6th of a second = [166 and 2/3] millisecondsSpeed = (wavelength) x (frequency) = 6 x 3 = [18] meters per second
The wavelength decreases. Frequency and wavelength are inversely related.
The speed of a wave = (wavelength) times (frequency) = (10) x (1/2) = 5 meters per second.
Frequency is the number of waves per second, i.e. 20Hz is 20 waves per second. Wavelength is obviously the length of each wave i.e 20m So if there are 20 waves per second, the distance it travels is the length of the wave multiplied by the number of waves in one second. The distance travelled in one second by the wave above is therefore 20 * 20m wich is 400m. The distance travelled in 1 second is 400m. Therefore every second, the wave travels 400m and thus the speed is 400meters per second (400m/s).
Period = (1) divided by (frequency) = (wavelength) divided by (speed)Frequency = (1) divided by (period) = (speed) divided by (period)Speed = (wavelength) times (frequency) = (wavelength) divided by (period)Wavelength = (speed) divided by (frequency) = (speed) times (period)
The first has half the wavelength of the second
radio waves
For any wave:speed = wavelength x frequency So, you must simply calculate the frequency first (it is 1/period), then multiply that by the wavelength.
Period = 1 / (frequency) = 1 / 6th of a second = [166 and 2/3] millisecondsSpeed = (wavelength) x (frequency) = 6 x 3 = [18] meters per second
The number of waves that pass a point in 1 second
Wavelength = speed / frequency300,000,000 meters per second/530,000,000 per second = 56.6 centimeters
The main properties of waves are defined below. * Amplitude: the height of the wave, measured in meters. * Wavelength: the distance between adjacent crests, measured in meters. * Period: the time it takes for one complete wave to pass a given point, measured in seconds. * Frequency: the number of complete waves that pass a point in one second, measured in inverse seconds, or Hertz (Hz). * Speed: the horizontal speed of a point on a wave as it propagates, measured in meters / second.
Speed, wavelength, frequency, period, amplitude, intensity.
monochromatic, coherent
Gamma rays are the waves with the shortest wavelength. The waves having highest frequency have the shortest wavelength. As gamma rays have the highest frequency starting from 10^19 and onwards so they have the shortest wavelength starting from 10^-11 and decreasing.
Wavelength = (speed) / (frequency) = (27/215) mile = 0.1256 mile (rounded)-- 663.06 ft (rounded)-- 202.1 meters (rounded)
