Label the parts of the wave provided:

c

d

Rarefaction

Compression

Trough

Crest

How do these waves compare?

• wave 2 has a higher frequency than wave 4

• all have the same frequency

• all have the same wavelength

• wave 3 has a longer wavelength than wave 4

Transverse waves carry energy ​ (a)   to the direction the medium is moving. 

A longitudinal wave carries energy ​ (b)   to the direction the medium is moving. 

• perpendicular
• parallel

Match the types of waves to their definitions:

• Longitudinal

• A disturbance that transfers energy from place to place

• Mechanical

• Energy that moves the medium at right angles to the direction the waves are traveling

• Electromagnetic

• A wave that only travels through a medium

• Wave

• A wave (such as a sound wave) that vibrates the particles of the medium parallel to the direction of the medium movement (back and forth)

• Transverse

• Waves can travel through empty space

Which color has the most energy?

Groups:

(a) Red

,

(b) Violet

• next to ultraviolet

• highest frequency

• shortest wavelength

• longest wavelength

• next to infrared

• most energy

• lowest frequency

• least energy

How are these waves different?

• The top wave has more energy because it has a higher amplitude.

• The top wave has more energy because it has a higher frequency.

• The bottom wave has more energy because it has a higher amplitude.

• The bottom wave has more energy because it has a higher frequency.
