When a wave is reflected while entering from rarer medium to a denser medium, then at the boundary, the reflected wave undergoes a phase change of
Correct answer: B. 180°
- A. 0°
- B. 180°
- C. 90°
- D. 45°
Explanation
When the transverse wave travels from the rarer medium to the denser medium, it gets reflected from the denser medium, where a phase change of π radian or 1800 occurs.

About Progressive Waves
Progressive waves transfer energy through a medium or space while particles oscillate about their equilibrium positions. The work includes amplitude, wavelength, frequency, period, phase difference, wave speed and the progressive wave equation, while distinguishing travelling waves from stationary waves, where the pattern has fixed nodes and antinodes.
