Exploring Wave Characteristics and Types

This lesson covers the characteristics of waves, including mechanical and electromagnetic types. It explains transverse and longitudinal waves, focusing on their properties like wavelength, amplitude, frequency, and period. The lesson also discusses how to calculate wave speed using these properties.

What is a wave in the context of physics?

• A sound in a sports event

• A physical movement of objects

• A movement of water only

• A disturbance that transfers energy without mass

What distinguishes a transverse wave from a longitudinal wave?

• The amplitude of the wave

• The frequency of the wave

• The speed of the wave

• The direction of particle oscillation relative to wave motion

How is wavelength measured in a wave?

• From trough to trough

• Both A and B

• From crest to crest

• From start to end of the wave

What does the amplitude of a wave represent?

• The wave's energy

• Both B and C

• The wave's height

• The wave's speed

How is frequency defined in the context of waves?

• The distance between crests

• The number of crests per second

• The height of the wave

• The speed of the wave
