A block of mass `M = 2kg` is suspended from a string AB of mass `6 kg` as shown in figure. A transverse wave pulse of wavelength `lambda_(0)` is produced at point B. find its wavelength while reaching at point A.

Text Solution

Verified by Experts

`lambda =(v)/(f) =sqrt(T//mu)/(f)`
or `lambda prop sqrt(T)` (as `mu` and if are constants)
`:. (lambda_(B))/(lambda_(A))= sqrt((T_(B))/(T_(A))`
`:. lambda_(B) = (sqrt(T_(B)/(T_(A)))) lambda_(A)`
`= [sqrt(((2+ 6)g)/(2g))]`
`=2 lambda`
