# Which type of wave can carry energy through a vacuum? (1 point)

O mechanical

O electromagnetic

O seismic

O sound

## The type of wave that can carry energy through a vacuum is an electromagnetic wave. To understand this, let's break down the options and explain each type of wave:

1. Mechanical waves: These waves require a medium, such as a solid, liquid, or gas, to travel through. Examples of mechanical waves include sound waves and seismic waves.

2. Electromagnetic waves: These waves do not require a medium to propagate and can travel through empty space, known as a vacuum. They are produced by an oscillating electric charge and consist of oscillating electric and magnetic fields that are perpendicular to each other. Examples of electromagnetic waves include radio waves, microwaves, infrared waves, visible light, ultraviolet waves, X-rays, and gamma rays. This is the correct answer to the question, as electromagnetic waves can carry energy through a vacuum.

3. Seismic waves: These waves are specific to the Earth's crust and are generated by earthquakes or other seismic events. They require a medium like the ground to propagate. Seismic waves are not able to carry energy through a vacuum.

4. Sound waves: These waves are mechanical waves that require a medium to travel through, such as air, water, or solids. Sound waves cannot travel through a vacuum, so they are not able to carry energy in that context.

In summary, among the given options, the type of wave that can carry energy through a vacuum is an electromagnetic wave.
