When wave is reflected from denser medium to rare medium then there is phase change of:
Correct answer: C. 0
- A. π/4
- B. π/2
- C. 0
- D. 2π
Explanation
When a wave is reflected from a denser medium to a rarer medium, the wave does not experience a phase change; thus, the correct answer is 0. In contrast, if the wave were reflecting from a rarer medium to a denser medium, it would undergo a phase change of π (or 180 degrees). Options suggesting phase changes of π/4, π/2, and 2π do not correctly reflect the behavior of the wave in this specific context.

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.
