How do sound waves travel between a boat and a submarine in sonar technology?

A. Because of water particles.
B. Because of water waves.
C. Because of water ripples.
D. Because of water currents.

Is it A?

G8 Electromagnetic Radiation

1. Mechanical waves require a medium to travel in; electromagnetic waves do not.

2. radio waves

3. X-rays have greater frequency then microwaves.

4. 3 Hz

5. Longitudinal, transverse, and surface

6. It is reflected.

7. water particles

8. A 10 liter container that has 5000 molecules.

9. They will be absorbed.

10. wave B; wave A

I assure you that these answers are correct relating to the Unit 3 Lesson 3 Quiz with 10 questions. I got 100% and actually found this quiz easier than I expected. Peace! ~ Jules

jules is 100 right I got a 100

Jules is 100% right, I got a 100%!!! Thanks!!!

Someone else said that it wasn't B.

the movement of the sound energy is in waves in the water.

Ok, I'm really confused. Sometime ago, PSYDag said that B wouldn't apply if the water was quiet.

I am thinking DAG was thinking of waves on the surface, like surfing. Sound waves are not like that, they are pressure waves underwater.

To be honest, the teacher here did not give good choices. A good choice has no ambiguity.

Yes, the correct answer is A. Sound waves travel between a boat and a submarine in sonar technology because of water particles. Sound is a mechanical wave that requires a medium, such as air or water, to travel through. When a sonar device emits a sound wave, it propagates through the water, causing the water particles to vibrate. These vibrating water particles then transmit the sound energy from the emitting source to the receiving device, such as a hydrophone on a submarine or a sonar receiver on a boat. By detecting the characteristics and timing of the returning sound waves, sonar technology can be used to measure distances, map underwater structures, and detect objects in the water.
