Question #3
When a wave travels from one medium to another, which of its properties never changes?
A. Frequency
B. Velocity
C. Amplitude
D. Wavelength

Correct Answer: Option A


Explanation:
When a wave (like light or sound) changes mediums, its velocity changes due to the new medium's optical or mechanical density. Wavelength changes proportionally with velocity (v = fλ). However, frequency is determined solely by the source generating the wave and the energy of the photons/particles, and it remains absolutely constant.
