Phase difference from time delay
Two SHM signals in a single-slit diffraction setup have period \(0.9\,\text{s}\) and time delay \(0.22\,\text{s}\). Calculate the phase difference in radians. Enter the numerical result and choose the interpretation that matches the wave physics.
Worked practice: physics data and result
Read the physical quantities first, then calculate the result and state what it means.
