Wave Properties and Characteristics

The video tutorial explains how waves transfer energy without moving matter, using the example of a Mexican wave. It covers key properties of waves: frequency, period, wavelength, and amplitude. Frequency is the number of complete waves passing a point per second, measured in Hertz. The period is the time for one complete cycle. Wavelength is the distance between similar points on consecutive waves, and amplitude is the height of the wave from its undisturbed position. The video concludes with a brief mention of future topics like wave speed.

What is the primary function of waves as described in the video?

• To generate light

• To move matter from one place to another

• To transfer energy without moving matter

• To create sound

How is the frequency of a wave measured?

• In seconds

• In meters

What does the frequency of a wave indicate?

• The height of the wave

• The time it takes for one complete cycle

• The number of complete waves passing a point in a given time

• The distance between two peaks

What is the period of a wave?
