Which type of wave needs a medium to travel? (1 point)
Olight waves, because they travel by oscillating molecules
O light waves, because they travel by oscillating electromagnetic fields
O sound waves, because they travel by oscillating molecules
O sound waves, because they travel by oscillating electromagnetic fields

Respuesta :

The type of wave which needs a medium to travel are sound waves because they travel by oscillating electromagnetic fields

What is a Sound Wave?

This refers to the waves of refraction which is propagated by a plastic medium.

With this in mind, we can see that mechanical waves are the types of wave that needs a medium for propagation and a sound wave is an example of a mechanical wave because it travels by oscillating electromagnetic fields.
