Wave Motion

The video introduces the concept of waves, explaining how they 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, while wavelength is the distance between similar points on consecutive waves. Amplitude is the height of the wave from its undisturbed position. The video concludes with a prompt to explore wave speed in future content.

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

• To change the color of light

• To transfer matter from one place to another

• To transfer energy without moving matter

• To create sound

How is frequency defined in the context of waves?

• The height of a wave from its undisturbed position

• The number of complete waves passing a point per second

• The distance between two peaks

• The time it takes for one complete cycle

Which of the following best describes the period of a wave?

• The distance between two consecutive troughs

• The number of waves passing a point in one second

• The time taken for one complete cycle

What is the wavelength of a wave?

• The time it takes for one complete cycle

• The number of waves passing a point per second

• The distance between a point on one wave and the same point on the next wave

• The height of the wave from the undisturbed position

What does the amplitude of a wave represent?

• The number of complete cycles per second

• The time for one complete cycle
