Question

Complete the passage.

Sound waves and some earthquake waves are ___ waves. Ocean, light, and other earthquake waves are ___ waves.

Answer 1

Sound waves and some earthquake waves are longitudinal waves. Ocean, light, and other earthquake waves are transverse waves.

Answer 2

longitudinal, transverse

Step-by-step explanation:

There are two types of wave motion

1. Longitudinal wave motion

2. Transverse wave motion

Longitudinal wave motion: When the particles of medium vibrates in the same direction of propagation of wave, it is called longitudinal wave motion.

For example, sound waves

Transverse wave motion: When the particles of medium vibrates in the perpendicular direction of the propagation of wave, it is called transverse wave motion. For example, light waves.

So, Sound waves and some earthquake waves are longitudinal waves. Ocean, light, and other earthquake waves are transverse waves.
