The video tutorial explains the concept of waves, using a Mexican wave as an analogy. It distinguishes between transverse and longitudinal waves, describing their oscillation directions. The tutorial covers wave properties such as amplitude, wavelength, and frequency, and explains how wave speed is calculated using these properties. An example calculation is provided, comparing the speed of a wave to the speed of light.

What is the main difference between transverse and longitudinal waves?

• Transverse waves oscillate parallel to energy transfer, while longitudinal waves oscillate perpendicular.

• Transverse waves oscillate perpendicular to energy transfer, while longitudinal waves oscillate parallel.

• Both types of waves oscillate in the same direction as energy transfer.

• Longitudinal waves do not involve oscillations.

Which of the following is NOT a characteristic of a wave?

• Density

• Frequency

• Wavelength

• Amplitude

What unit is used to measure the frequency of a wave?

• Joules

• Hertz

• Seconds

• Meters

How is the speed of a wave calculated?

• By adding frequency and wavelength

• By multiplying frequency by wavelength

• By subtracting frequency from wavelength

• By dividing wavelength by frequency

Which wave travels faster: sound or light?

• Sound

• Light

• They travel at the same speed

• It depends on the medium
