Wave Properties and Behavior

The video explains the concepts of waves, focusing on transverse and longitudinal waves. It covers the properties of waves, such as crest, trough, amplitude, and wavelength. The video also discusses wave equations, including speed, frequency, and period. Transverse waves have perpendicular oscillations to wave motion, with examples like water and electromagnetic waves. Longitudinal waves have parallel oscillations, exemplified by sound waves, with regions of compression and rarefaction.

What is the top part of a wave called?

• Crest

• Wavelength

• Amplitude

• Trough

How can the speed of a wave be calculated?

• By subtracting frequency from wavelength

• By adding wavelength and frequency

• By multiplying wavelength by frequency

• By dividing wavelength by frequency

What unit is used to measure frequency?

• Meters

• Seconds

• Hertz

• Newtons

In a transverse wave, how do the oscillations move relative to the wave direction?

• Parallel to the wave direction

• In a random direction

• In a circular motion

• Perpendicular to the wave direction

Which of the following is an example of a transverse wave?

• Seismic wave

• Water wave

• Pressure wave

• Sound wave

What is a characteristic of longitudinal waves?

• Oscillations are perpendicular to wave motion

• Oscillations are parallel to wave motion

• They do not have oscillations

• They move in a circular pattern

Which of the following is a good example of a longitudinal wave?

• Gamma ray

• Radio wave

• Light wave

• Sound wave

What happens in the regions of compression in a longitudinal wave?

• Molecules move in a circular pattern

• Molecules are close together

• Molecules are spread out

• There is no change in molecule density

How do the oscillations in transverse waves differ from those in longitudinal waves?

• They are parallel in transverse and perpendicular in longitudinal

• They are perpendicular in both

• They are parallel in both

• They are perpendicular in transverse and parallel in longitudinal

Which type of wave has oscillations that are perpendicular to the direction of wave motion?

• Neither type

• Longitudinal wave

• Transverse wave

• Both types
