When I plug in vListener/λ that goes to zero in both the numerator and the denominator. I am just left with (v/λ)/(v/λ)=2^1/12 will the v divided by lamdas equal 1. 1 is not equal to 2 1/12?

No, He ended class with interference. So I am just trying to figure this out by watching videos online and stuff. I tried doing the next two problems and I got them wrong (see the pic for the work) So that is why i am confused!

Frequency of the Listener = ( (v+vL)/(v+vs) )* Frequency of source 2^ 1/12:( I'm not sure I'm understanding how to find my other variables.

The only thing I can think of this that from A, if they are saying that the frequency ratio is 2^(1/12), then If I want to find the Period, T=1/f or T= 1/ 2^(1/12) = 0.9438 ?

Could you explain How i should set up part b.

yayy! I typed in 12 rad 2 and i got it right!

hmmmm okay. thanks for those links. So do you think they just want me to type in 12 rad 2 for part A. I kind of don't get it. I saw for b, that the distances are equally apart.

They don't give me any numbers for part B.

The title of the question is "Musical Scale." Part A seems so confusing to me. That is all they gave in the question. :/

Homework Statement The frequency ratio of a semitone interval on the equally tempered scale is 2 1/12. A) Show that the ratio is 1.059 B) Find the speed of an automobile passing a listener in still air if the pitch of the car's horn drops a semitone between the times when the car is...

okay so : 0+(-1.25 rev/s^2)(4 sec)+ 1/2(-1.25 rev/s^2)(4^2) x=-5.00+ -12.50 x=-17.50 how do i make this angular?

i don't have xo right? we didn't cover this yet...

ohhhhhhhhhhh... ok thanks. hmmm... I'm not sure what formula i should use. i was going to try x=xo+vot+1/2at^2 but i can;t. .....
