Statement-1: When a wave travels from a lighter string to a heavier string, it undergoes a phase change of radians upon reflection.
Statement-2: The frequency of a wave remains unchanged when it passes from one medium to another.
Options:
Answer:
B
Solution:
When a wave reflects from a denser medium (heavier string, fixed end equivalent), it undergoes a phase change of radians (or ). So, Statement-1 is true. The frequency of a wave is determined by its source and remains constant when it travels from one medium to another, while its speed and wavelength change. Thus, Statement-2 is also true. Statement-2 is a general property of waves and does not explain the phase change upon reflection.
