Phase difference is [2(Pi)x]/Lambda
Lambda is 50
[2×(Pi)×20]/50
= (4/5)Pi

the diff. btw them is what we are ask to fimd. soo 50cm/20cm =5/2.

phase difference equals kx where k from the wave equation equals 2#x/lambda ...substitute the values given above 2*20*#/50=40#/50 ans =4#/5 i.e c

phase difference(@) is equal to 2pi.X/L where x=20cm nd l=wave length= 50. der4 d phase diff. = 2pi *20/50=40pi/50 = 4pi/5. option C.
