17 oct 2008 · Example 2 If the frequency of a wave is 4 Hz, what is its period? T = 1 ? = 1 4 = 0 25 s
Speed, wavelength, and frequency of a wave are related by v =??f We can rearrange this to get???= v/f or f = v/? (a) For AM radio waves:
frequency and wavelength, but this is not the case – the speed is determined by the medium A good example is the speed of a wave on a stretched string
A classic example is a wave traveling down a line of standing dominoes: each wave speed equals wavelength times oscillation frequency
the source is making the sound, then the observer hears a frequency f given by: 6 2 Worked Examples Unless otherwise specified, we will take the speed
Figure 3-2 shows examples of signals that differ in frequency The term amplitude is a bit different from the other terms that have been discussed thus far,
The frequency of sound is the For example, cats can detect frequencies that are much lower, http://physics tutorvista com/waves/wave- · frequency
AQA GCSE Physics (Separate Science) Unit 6: Waves The frequency of a wave is the number of waves which pass a given point Examples of this type
A wave on a string has the formula y = 0 030sin(0 55x − 62 8t + π/3) What is the wavelength, frequency, period, phase constant, and speed of the wave
distance over time, so v = λ / T The frequency, f, is 1/T, so the equation relating wave speed, good example is the speed of a wave on a stretched string
Example: wave on a string • A wave moves on a wavelength,λ is 2 cm, what is the frequency, ƒ ? • v = λ × ƒ, so ƒ = v frequencies of your sounds is twice as
