What is the phase difference between two points on a wave that are half a wavelength apart?
Correct Answer: π radians
Step 1: Understand what a wavelength is. A wavelength is the distance between two consecutive points on a wave that are in the same phase (like two peaks or two troughs).
Step 2: Know that a full wave (one complete cycle) corresponds to a phase change of 2π radians.
Step 3: Realize that half a wavelength is half of the full wave. Therefore, half a wavelength corresponds to a phase change of 2π radians divided by 2.
