What happens whenever a transverse wave travelling in a denser medium, is reflected from the boundary of the rarer medium?

Explanation

Option A: The direction of its displacement remains the same: This means that when the transverse wave reflects from the boundary between the denser and rarer medium, the wave continues to oscillate in the same direction as it did before reflection. The amplitude of the wave may change, but its direction of displacement remains unchanged.Option B: The direction of its displacement is reversed: This option states that the wave's displacement direction is reversed upon reflection. However, this is incorrect for a transverse wave. In transverse waves, the particles of the medium vibrate perpendicular to the direction of wave propagation, and when reflected, the wave maintains its original direction.Option C: The displacement disappears: This option suggests that the displacement of the wave disappears upon reflection. However, this is not the case. The wave still carries energy and exhibits displacement after reflection.Option D: The displacement becomes double: This option implies that the displacement of the wave becomes double upon reflection. However, reflection does not alter the magnitude of the displacement of a transverse wave. The amplitude of the wave may change due to other factors, but it does not become double as a result of reflection.
