Question

True or False. Electromagnetic waves cannot travel through a vacuum.

Answer 1

Electromagnetic waves do not need a medium to travel. This means that it can travel through air, water and ultimately, a vacuum. Thus, the statement is false

Answer 2

The provided statement about electromagnetic waves is FALSE.

• Electromagnetic waves can travel in space without material medium because it does not require any particular matter to traverse throughout.
• These waves can travel as a space and time component.
• The electric field is created by the electrons. When there is an alteration in the electric field it produces a magnetic field. These waves travel perpendicular to each other and keep changing from electric waves to magnetic waves and vice versa at time intervals.
• As it is a vibration of space itself it can even travel through the vacuum.
• Mechanical energy requires a medium to travel as one particle transfers energy to another whereas EM waves transfer energy without any material medium.
• An example of these waves is light waves.
• Hence, the given statement is incorrect.
