InterviewSolution

1.	In standard AM broadcast, what mode of propagation is used for transmitting a signal? Why is this mode of propagation limited to frequencies upto a few MHz?
Answer» In standard AM broadcast, ground wave is used as mode of propagation.This mode is limited up to a few MHz, because the attenuation of surface waves increases very rapidly with increase in frequency.
