What do sound waves and infrared waves have in common, and what makes them different?

A
Both carry energy through space, but sound waves are mechanical and infrared waves are electromagnetic.
B
Both can transfer energy through matter, but sound waves travel through air and infrared waves travel through space.
C
Both can transfer energy through matter, but sound waves can be heard and infrared waves can be seen.
D
Both carry energy through space, but sound waves require matter to pass through and infrared waves do not.

Which statement applies to transverse waves?

A
The waves have a trough.
B
Particles move great distances.
C
The waves have alternating compressions and expansions.
D
The energy is transferred parallel to the direction of the wave motion.

A
A wave is like building a ramp.
B
A wave is like shaking a hand.

Venn diagrams are used for comparing and contrasting topics. The overlapping sections show characteristics that the topics have in common, and the sections that are unique to each topic show the characteristics that apply to only that topic. This Venn diagram is comparing mechanical and electromagnetic waves.

Question illustration
A
“Carry energy through space” and “Follow a pattern”
B
“Carry energy” and “Follow a pattern”
C
“Carry energy through space” and “Can be heard”
D
“Carry energy” and “Can be heard”
9

What is the motion of the particles in this kind of wave?

Question illustration
A
The particles will move up and down over large areas.
B
The particles will move up and down over small areas.
C
The particles will move side to side over small areas.
D
The particles will move side to side over large areas.

2 circles with an overlap. The left circled is labeled Longitudinal Wave with further labels parallel motion, like moving a spring up and down. The right circle is labeled Transverse Wave with further labels perpendicular motion, like moving a spring back and forth. In the overlap are labels particles only move a small amount, particles do not move with the wave.

Question illustration
A
“Parallel” and “Perpendicular” are switched.
B
The spring descriptions of motion are switched.
C
Particles travel along the wave in longitudinal waves.
D
Particles move long distances in transverse waves.
