Question

How do I determine the wave speed from given frequency and wavelength?

Answer 1

Hint :Within the case of a wave, the speed is that the distance traveled by a given point on the wave (such as a crest) during a given interval of your time. In equation form, If the crest of an ocean wave moves a distance of 20 meters in 10 seconds, then the speed of the ocean wave is 2.0 m/s.

Complete Step By Step Answer:
Speed = Wavelength x Wave Frequency. During this equation, wavelength is measured in meters and frequency is measured in hertz (Hz), or number of waves per second. Therefore, wave speed is given in meters per second, which is that the SI unit for speed.
The relationship between the frequency (the number of wave crests that travel by a particular point during a given amount of time) and wavelength for electromagnetic waves is defined by the formula, c = λ f, where c is that the speed of sunshine, λ the wavelength in meters, and f equals the frequency in cycles per second.
Assuming a sinusoidal wave moving at a hard and fast wave speed, wavelength is inversely proportional to frequency of the wave: waves with higher frequencies have shorter wavelengths, and lower frequencies have longer wavelengths.

Note :
Frequency: is that the number of waves that pass a particular point during a specified amount of your time trough: The low point of the wave cycle. Wavelength: the space between two successive peaks. The frequency of a photon is defined as what percentage wavelengths a photon propagates each second. Unlike electromagnetic radiation, a photon cannot actually be of a color.
