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.

What is frequency primarily measured in?

• Counts per unit time

• Meters per second

• Joules per second

• Kilograms per cubic meter

What is the SI unit of frequency?

• Watt

• Pascal

• Hertz

• Newton

How is Hertz defined in terms of a waveform?

• The number of meters per second

• The number of cycles per second

• The number of vibrations per minute

• The number of waves per hour

What does frequency measure in terms of vibrations?

• The speed of light

• The number of complete vibrations or cycles in a unit of time

• The distance between two points

• The energy of a system

Which of the following best describes frequency?

• A measure of energy

• A measure of time

• A measure of cycles or vibrations per unit time

• A measure of distance
