1.Describe an environment in which the sound of a ringing cell phone could not be transmitted, and explain why the ringing wouldn't be heard.




2.Explain what happens to the pitch of a cell phone ring when the amplitude of a sound wave increases.







3.Explain what happens to the pitch of a cell phone ring when the wavelength of a sound wave increases.









4.As a communication engineer what would you do to make sure everyone has cell service during an emergency like hurricane Harvey. Your plan can include a new device to assist in telecommunications or steps that can be taken to reduce the impact of a mass outage after a hurricane.

Answer 1

Hello!

1) One place might be a soundproof room. The sound bounces off the walls until it eventually loses its momentum until it stops.

2) As the amplitude increases so does the pitch.

3) It would increase the pitch

4) Just build underground lines

I hope it helps!

Answer 2

this middle school?
1.) if you place the cell phone in a soundproof room, leave and close the door, when the cell phone rings the sound waves will travel through the room; slowly losing their momentum everytime they hit an object.
2.) increased amp would equal a higher pitch

3.) increased weave would increase the duration of the pitch

4.) this one is on you; use your imagination - just keep it real (don't go against the laws of physics)
