A rocket is moving towards a stationary wall while moving it emits a wave of frequency 1000 Hz some of the sound gets reflected back to the rocket as an echo calculate the frequency of the echo as detected by the rocket
Consider similar rocket moving opposite to the givwn rocket virtually from other side of wall
Please solve it as I've tried it and answer is not matching
ok i will try...
What is the velocity of the rocket?
Answer is 1000.00133Hz?
I am not getting it exactly as 4080 with the speed of sound as 330 m/s is there anything given to take as speed of sound?
I was applying Light Doppler Effect!
Bro it's taking too much time to upload but I am getting answer 4080 just apply normal formula with v-vs and v+vo and u will get exact answer with v=332
They have given the speed of sound as 330m/s @shivansh_pandey please send the solution
By that the answer will come around 4030hz...with 332 it will come 4077hz bro it's not uploading...I will try after 15mins to upload again
@shivansh please write your solution and send it
F=F°[v+vo/v-vs] ...F°=1000hz....Vo=Vs=200m/s...u can put values now
Yes bro that's what I was saying too😄
@Raj_1 why did you take vo as 1000*330/130,it should be 1000 itself because as the rocket has produced the sound it will have same frequency with respect to it initially right?
Where have i taken vo as 1000×330/130?
That is the frequency received by the wall!
