Question

Distinguishing Types of Waves through Examples

A 2-column table with 3 rows. The first column labeled mechanical waves has entries ocean water, light waves, earthquake waves. The second column labeled electromagnetic waves has entries sound waves, radiation waves, X-ray waves.

How should the table be changed to correctly distinguish between mechanical and electromagnetic waves?

Earthquake waves and radiation waves need to change places.
Light waves and X-ray waves need to change places.
Ocean waves and X-ray waves need to change places.
Sound waves and light waves need to change places.

Answer 1

Sound waves and light waves need to change

Step-by-step explanation:

Answer 2

Sound waves and light waves need to change places.

Step-by-step explanation:

Given table:

Mechanical waves Electromagnetic waves

Ocean water Sound waves

Light waves Radiation waves

Earthquake waves X-ray waves

From the given table, to be correct, light and sound waves must change their position.

Light wave is an electromagnetic wave

Sound wave is a mechanical wave

An electromagnetic wave does not require a material medium for propagation.

Mechanical waves require material medium for their propagation.

Mechanical waves Electromagnetic waves

Ocean water Light waves waves

Sound waves Radiation waves

Earthquake waves X-ray waves
