An oscilloscope is a useful tool for anyone working with electrical signals because it provides a visual representation of the signal's shape, or waveform. This allows you to measure properties of the wave, such as amplitude or frequency. The initial signal above is a 200Hz sine wave, which has an amplitude of 5 volts.
A wave’s crest is its highest point, and its trough is its lowest point. A wave’s amplitude is the maximum distance (positive or negative) a wave reaches from its rest position. Wavelength is the distance between the same spot on two sections of a wave.
The amplitude of a wave is a measure of the displacement of the wave from its rest position. The amplitude is shown on the graph below. Amplitude is generally calculated by looking on a graph of a wave and measuring the height of the wave from the resting position.
11 Ιαν 2023 · You can read from the plot the amplitude of the wave, \(A=2\) cm, and the wavelength, \(\lambda=4\) m. The plot on the right show the oscillation of the medium at \(x=3\) m as a function of time. It shows the same amplitude which has to be consistent between the two plots.
Adjust frequency and amplitude, and observe the effects. Hear the sound produced by the speaker, and discover what determines the color of light. Make waves with a dripping faucet, audio speaker, or laser!
28 Δεκ 2020 · Electromagnetic waves can come in many different wavelengths and different frequencies, so long as the product of the wavelength and frequency of a given wave equals the speed of light (that is, λf = c).
