A ligth string
A light string is attatched to a heavy rope, and the whole thing is pulled tight. A wave is sent along the light string. When it hits the heavy rope, compared to the wave on the string, the wave that propagates along the rope has the same (A) frequency (B) wavelength (C) both frequency and wavelength (D) neither?
Homework Answers
(A) frequency
we know, wave speed on a string, v = sqrt(T/mue)
T ---> tension
mue ---> linear mass density
and, f = v/lamda
so, wave speed (v) and wavelength(lamda) values change but frequency remainse same.

You generate a standing wave on a 1-m long string, fixed on both ends, by forcing it to vibrate at 100 Hz. When doing so, the standing wave has a wavelength of 1 m. According to the wave equation, v=Af, the speed of the wave along the string is 100 m/s. Suppose the forcing frequency is doubled to 200 Hz, without changing the length, tension or ends of the string. What is the new wavelength and wave speed? A. The...
