centripetal acceleration is given by formula

given that


now we have




so the ratationa frequency is given by




B. Transverse Wave this is the correct answer
This contraption is a lot of fun, and you really should try it
some time.
The sound waves move from one can to the other one
by traveling through the string.
Answer:
a)
b)
Explanation:
a)
The width of the central bright in this diffraction pattern is given by:
when m is a natural number.
here:
- m is 1 (to find the central bright fringe)
- D is the distance from the slit to the screen
- a is the slit wide
- λ is the wavelength
So we have:
b)
Now, if we do m=2 we can find the distance to the second minima.

Now we need to subtract these distance, to get the width of the first bright fringe :
I hope it heps you!
