Question

when a transverse wave on string is reflected from the free end the phase chamges produce is a) zero rad b) 3 pie / 4 c) pie /2 d ) pie rad​

Answer 1

Answer:

Phase change - 0 radian

when it reflects from close end

phase Change - π rad(180°)

ex -

free end

Ek wave He

eq - Asin(wt-Kx) travelling in +x direction

After reflected from free end

eq - Asin(wt+Kx) travelling in -x direction
