This video tutorial covers the fundamental properties of waves, including wavelength, amplitude, frequency, wave speed, and period. It explains how to measure these properties using a drawn wave example, introduces the Greek letter lambda for wavelength, and discusses the unit Hertz for frequency. The tutorial also demonstrates how to calculate wave speed and period, providing a comprehensive understanding of wave dynamics.

What does the wavelength of a wave represent?

• The speed at which a wave moves through space

• The maximum distance a wave moves from its rest position

• The distance between two equivalent points on a wave

• The number of times a wave passes a point each second

What symbol represents wavelength?

• Lambda (λ)

• F

• T

• V

How is amplitude measured in a wave?

• From crest to crest

• From trough to trough

• From the rest position to a crest or trough

• From the beginning to the end of the wave

How is the amplitude of a wave determined?

• By counting the number of waves in a second

• By measuring the speed of the wave

• By calculating the distance from the rest position to a crest

• By measuring the distance between two troughs

What unit is used to measure frequency?

• Meters

• Centimeters

• Hertz

• Seconds

If the frequency of a wave is 4 Hz, what does this mean?

• The wave moves at 4 meters per second

• The wavelength of the wave is 4 centimeters

• The wave has 4 crests and troughs in one second

• There are 4 waves passing a point each second

How do you calculate wave speed?

• Frequency multiplied by amplitude

• Wavelength multiplied by frequency

• Frequency divided by wavelength

• Wavelength divided by frequency

What is the period of a wave?

• The maximum height of a wave

• The number of waves that pass a point per second

• The distance between two crests

• The time it takes for one wave to pass a point

What is the relationship between wave speed, wavelength, and frequency?

• There is no relationship between these properties

• Wave speed equals wavelength plus frequency

• Wave speed equals wavelength divided by frequency

• Wave speed equals wavelength times frequency
