Question

Which statement is true about electromagnetic and mechanical waves? (1 point)

Responses

Electromagnetic waves travel slower than mechanical waves.
Electromagnetic waves travel slower than mechanical waves.

Electromagnetic waves all have the same frequency but mechanical waves occur with different frequencies and wavelengths.

Electromagnetic waves are transverse, but mechanical waves are longitudinal.
Electromagnetic waves are transverse, but mechanical waves are longitudinal.

Electromagnetic waves can travel without a medium, but mechanical waves require a medium to travel.
Electromagnetic waves can travel without a medium, but mechanical waves require a medium to travel.

Answer 1

The statement "Electromagnetic waves can travel without a medium, but mechanical waves require a medium to travel" is true about electromagnetic and mechanical waves.

Answer 2

are you sure

Answer 3

Yes, I am sure. Electromagnetic waves, such as light waves, can travel through vacuum or empty space without the need for a medium. On the other hand, mechanical waves, such as sound waves, require a medium, such as air or water, to propagate.

Answer 4

a b c or d
