The standing wave ratio on a 50 Ω lossless transmission line terminated in an unknown load impedance is found to be 2.0. The distance between successive voltage minima is 30 cm and the first minimum is located at 10 cm from the load. ZL can be replaced by an equivalent length lm and terminating resistance Rm of the same line. The value of Rm and lm, respectively, are
A
Rm = 100 Ω, lm = 20 cm
B
Rm = 25 Ω, lm = 20 cm
C
Rm = 100 Ω, lm = 5 cm
D
Rm = 25 Ω, lm = 5 cm

Correct : d
