Question

Sound Waves: The frequency of sound waves can be measured using a device called a microphone. The microphone converts the sound wave into an electrical signal, which can then be analyzed using an oscilloscope or a frequency counter to determine the frequency.

2. Light Waves: The frequency of light waves, specifically in the visible spectrum, can be measured using a device called a spectrometer. A spectrometer splits light into its component colors and measures the frequency of each color using a diffraction grating or other optical components.

3. Electromagnetic Waves: The frequency of electromagnetic waves, such as radio waves or microwaves, can be measured using a device called a frequency counter or a spectrum analyzer. These devices can capture the electromagnetic wave and determine its frequency by analyzing the frequency components of the captured signal.

In general, the frequency of a wave can also be determined by measuring the time it takes for one complete cycle of the wave to pass a particular point, and then calculating the reciprocal of that time. For example, if it takes 0.01 seconds for one complete cycle, the frequency would be 1/0.01 = 100 Hz.

Answer 1

Frequency of sound waves can be measured using a microphone and analyzing the electrical signal through an oscilloscope or frequency counter. Light waves can be measured using a spectrometer that splits light into different colors and measures their frequencies. Electromagnetic waves can be measured using a frequency counter or spectrum analyzer by analyzing the frequency components of the captured signal. The general method of measuring frequency is by calculating the reciprocal of the time it takes for one complete cycle to pass a point.
