I WONDER - How Are Sound And Water Waves Different?

The video tutorial explains two types of waves: mechanical and electromagnetic. Mechanical waves, like sound and water waves, require a medium such as air, water, or solids to travel and cannot move through a vacuum. In contrast, electromagnetic waves, including light, radio waves, and X-rays, can travel through a vacuum, allowing sunlight to reach Earth from the sun through space.

What are the two main types of waves discussed?

• Mechanical and Sound

• Electromagnetic and Light

• Sound and Water

• Mechanical and Electromagnetic

Which of the following is a characteristic of mechanical waves?

• They are faster than electromagnetic waves.

• They require a medium to travel.

• They include X-rays.

• They can travel through a vacuum.

Which medium is NOT required for mechanical waves to travel?

• Water

• Air

• Solid

• Vacuum

Which of the following is an example of an electromagnetic wave?

• Seismic wave

• Sound wave

• Water wave

• Radio wave

Why can sunlight reach Earth from the sun?

• Because mechanical waves can travel through a vacuum.

• Because electromagnetic waves can travel through a vacuum.

• Because it travels through water.

• Because it travels through air.
