Image Credit: NASA. The electromagnetic spectrum is comprised of all frequencies of electromagnetic radiation that propagate energy and travel through space in the form of waves. Longer wavelengths with lower frequencies make up the radio spectrum.
11 Ιαν 2023 · A wave that spreads outward in all directions is a three-dimensional wave. Examples of three-dimensional waves are typical sound and light waves. An important distinction between these waves is that the amplitude \(A\) of the waves is only constant for one-dimensional waves.
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.
11 Ιαν 2024 · amplitude – The maximum displacement of an harmonic wave depends upon how much the driver displaces the medium at the source of the wave. We also found that the amplitude can change (get smaller) when the wave is radiating outward from a point source in 2 or 3 dimensions.
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!
