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.
6

Which is a characteristic of all waves?

A
All waves carry energy.
B
All waves move through space.
C
All waves move through matter, from particle to particle.
D
All waves transfer energy perpendicular to the direction of wave motion.

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”

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.
