Wave Properties and Behavior

The video tutorial explains how energy transfers through mechanical waves, which require a medium. It covers three types of mechanical waves: transverse, longitudinal, and surface waves. Transverse waves have crests and troughs, while longitudinal waves have compressions and rarefactions. Surface waves combine properties of both transverse and longitudinal waves. The tutorial also discusses wave characteristics such as wavelength, amplitude, period, and frequency, and how these relate to wave speed.

What is the medium for the sound waves produced by a person speaking?

• Metal

• Solid Earth

• Air

• Water

In a transverse wave, how do the particles of the medium move in relation to the direction of the wave?

• Perpendicular

• Parallel

• Circular

• Randomly

What is the term for the highest point a transverse wave reaches?

• Crest

• Trough

• Rarefaction

• Compression

How is the amplitude of a wave correctly measured?

• From trough to crest

• From rest position to trough

• From crest to rest position

• From crest to trough

In a longitudinal wave, what are the areas where particles are bunched together called?

• Crests

• Compressions

• Rarefactions

• Troughs

Which type of wave is a sound wave an example of?

• Electromagnetic wave

• Surface wave

• Longitudinal wave

• Transverse wave

What is unique about the motion of particles in surface waves?

• They do not move at all

• They move in a circular pattern

• They move only perpendicular to the wave direction

• They move only parallel to the wave direction

What is the period of a wave?

• The distance between two crests

• The height of the wave

• The time it takes for a wave to repeat itself

• The speed of the wave

How are period and frequency related?

• They both measure wave speed

• They are unrelated

• They are inverses of each other

• They are the same

If the wavelength of a wave is 2 meters and the period is 1.54 seconds, what is the wave speed?

• 2.0 meters per second

• 1.3 meters per second

• 3.08 meters per second

• 0.77 meters per second
