Question

Mark correct option

• A. the phase of transmitted wave always remains unchanged
• B. the amplitude of transmitted wave does not depend upon the velocity of wave in media
• C. the sum of amplitudes of reflected wave and transmitted wave is equal to amplitude of given incident wave
• D. the amplitude of reflected wave.is equal to the amplitude of incident wave

Answer 1

Answer: (A)

During the transmission of a wave from one to another media the amplitude of wave changes since it depends on velocities of wave in different media.
But whatever the value of velocities the amplitude of transmission always remain positive so phase remain unchanged.
