Question

In which of the following situations do the particles of the medium oscillate only parallel to the motion of the wave?

energy transmitted by the cry of an eagle
energy transmitted by ocean waves
energy used to microwave food energy used in cellular communication

Answer 1

Hi!

I believe the answer is A . energy transmitted by the cry of an eagle.
The particles of the medium oscillate only parallel to the motion of the wave transmitted by the cry of an eagle .

Hope it helps and have a wonderful day !

Answer 2

energy transmitted by the cry of an eagle

Step-by-step explanation:

There are two type of waves

1) Transverse waves: here medium molecules will oscillate perpendicular to the direction of propagation of energy in the medium.

Here examples of transverse waves are

Light waves, all electromagnetic waves, string waves etc

2) Longitudinal wave: here medium molecules will oscillate parallel to the propagation of energy through the medium.

Here examples of longitudinal waves are

Sound waves etc

So in this examples we need to choose the situation where medium molecules will oscillates parallel to motion of wave which must be sound wave

so correct answer is

energy transmitted by the cry of an eagle
