When l/λ is very small, transmission-line effects may be ignored, but when 17. is approximately greater than .............. it may be necessary to account not only for the phase shift due to the time delay, but also for the presence of ............ signals that may have been bounced back by the load toward the generator.
a) 0.01, reflected
b) 1.01, refracted
c) 0.001, transmitted
d) 0.05, incident
e) none
ANSWER
When lambda/2 is very small, transmission-line effects may be ignored, but when lambda/2 is approximately greater than 0.01, it may be necessary to account not only for the phase shift due to the time delay, but also for the presence of reflected signals that may have been bounced back by the load toward the generator.
The reflected signals gets bounced back due to value of lambda beyond 0.01.
