1) A transverse wave of frequency 25 Hz propa-
gates down a string. Two points 30 cm apart
are out of phase by (5*pi)/3
What is the wave length of the wave? An-
swer in units of cm.
Im kinda lost here, I am unsure how wave length will relate to the given info. I am sure the phase is part of the relation but I am unsure of how. The best I've been able to figure so far would be converting the frequency to a period, then using v= lambda/T.
I suppose phase is key to solving this problem, but maybe I am unsure of exactly how phase relates?
2) Given two equations Y1 = A / (Bx - Ct)^2 Y2= -A / (Bx + Ct - E)^2
At what time will the two waves exactly cancel everywhere? At what point do the waves always cancel?
Ive been reading in my book about this problem and I am unsure exactly what the case is for two waves to cancel each other out. I would assume they have to be exactly out of phase with each other, so that the peak of one corresponds with the valley of another. Although I am unsure how to meet this condition in the above equations.
Thanks for any help!
