this is from my physics assignment... after pulling half of my hair, i still couldn't figure it out...
my answer for part a) is greater and lower
and part b) is same and same...
not sure tho...
thx
4. Part a) A sister has a ball which she throws toward her brother. The ball is thrown...
Consider a situation in which a light source is stationary with respect to an observer, A. This source emits n photons of frequency f, each of energy E = hf, towards A. Hence, A will be able to detect the energy loss in the source, which is E = nhf.
Now, this light source is moving with...
Using the doppler effect: formula: f'=f/(1-V_s/V_0)
A train traveling toward you at 120k/h. the train blows its 400Hz whistle. take the speed of sound to be 340m/s. what's the freq?
my developments so far...
400Hz/(1-(.340/.343ms)
how do i solve the setup is wrong?
I have a question regarding waves which has been bugging me for a while:
"You are given a traveling wave with an equation of the form
cos(ax+/-bt)
where x and t are position and time as usual, a and b are positive numbers. Explain how you would physically determine the direction that the...
