Q15
Transverse wave of amplitude 10 cm is
generated at one end (x = 0) of a long
string by a tuning fork of frequency 500
Hz. At a certain instant of time, the
displacement of particle A at x = 100 cm
is - 5 cm and of particle B at x = 200 cm is
+ 5 cm. what is the wavelength of the
wave?​

ANSWER

Amplitude =0.05m=5m

Points A & B can be

Point A is a trough & Point B is a rest, as shown in figure

As, it isn't given whether A & B are consecutive rests and troughs

Given distance between A & B=1m

From (i)

For the simplest case: n=0 adjacent rest & trough.

λ=2m.
