Question

all waves that travel through matter are called
a surface waves.
b transverse waves.
c mechanical waves.
d longitudinal waves.

Explanation:

To solve this, we analyze each option:

• Option a: Surface waves are a type of mechanical wave that travel along a surface, not all waves through matter.
• Option b: Transverse waves are a type of mechanical wave where particles move perpendicular to wave direction, not all matter - traveling waves.
• Option c: Mechanical waves are defined as waves that require a medium (matter) to travel through. This matches the description "waves that travel through matter".
• Option d: Longitudinal waves are a type of mechanical wave where particles move parallel to wave direction, not all matter - traveling waves.

Answer:

c. mechanical waves
