Frequency

The video tutorial explains frequency as a measure of how many complete cycles or vibrations occur in a unit of time. It introduces the SI unit of frequency, Hertz, which represents the number of cycles per second for a waveform.

Describe the relationship between frequency and waveforms.

• Frequency determines the shape of the waveform

• Frequency is unrelated to waveforms

• Frequency affects the amplitude of the waveform

• Frequency indicates the number of complete vibrations

Explain what is meant by cycles occurring in a unit of time.

• The total number of vibrations

• The duration of each cycle

• The frequency of the waveform

• The energy of the wave
