How to do that Physx Sound Question...????

[Zaeem Khalid]

it was in Section B Second Question

What was the value of the number of waves sent in one second????
Please help.

166667 hz

 

[Zaeem Khalid]

Is this confirmed?

The Question stated that the waves emitted by the source not the waves reflected back. so you would use number of waves 5 not 4.....

 

[Mobeen]

yes.. the answer was 166666.666666 = 166667

 

[Zaeem Khalid]

using 5 brings
208333.3333
but using 4 the answer brings
166666.66666
...

 

[Zishi]

using 5 brings
208333.3333
but using 4 the answer brings
166666.66666
...

Yeah. We had to use five. So, the answer was 208333

 

[Mobeen]

we had to use 4

 

[Zishi]

we had to use 4

Give me the explanation, then. Each pulse was being sent after 5x10^-6 seconds. =/

 

[Mobeen]

yar i dont remember the question exactly .. i just know tht the answer was 166 666 ... nd as far as i can recall this was corect ..

 

[Zaeem Khalid]

Yar Moheen and Zishi Listen, I almost spent 15 minutes on this question. The Question Stated " How many Waves were emitted by the source in one second"
The emitted waves by the source were 5 but the reflected waves were 4 so I think that we had to use 5 because the question stated that the source.
What do u think?

 

[Zishi]

I'm 100% sure that we'd to use 5.

 

[Zaeem Khalid]

Yes I know...I'm also a bit sure.

 

[Mobeen]

its mobeen ..not moheen ..

 

[Mobeen]

yar as i dont remember the question .. i wont argue on tht... lets just hope for the best .. .

 

[Zaeem Khalid]

Oh! Sorry...Mobeen wat do u think?
We had to use 5 correct?

 

[Mobeen]

yar .. i even dont remember which , 4 or 5 , i used .. my answer was 166 666 ... nd i really thought abt it before doin it ..

it was 166667. I did 208something too but when i rechecked my paper i found that 1666667 was correct.

 

[Zaeem Khalid]

Yaar but the waves sent by the source were 5 not 4...

 

[BILALrox01]

Yes but you are looking at 5 waves but the time BETWEEN those was 4 WAVES.
