Waves questions and practice

Connect wavelength, phase and interference with the patterns you can see.

Waves and interference questions

Calculate phase, fringe spacing and string harmonics; add wave displacements.

Read voltage amplitude, peak-to-peak voltage, period, frequency and phase difference.

Convert line density, calculate wavelength and angles, and check allowed diffraction orders.

Start with waves and interference, then apply the grating equation or read an oscilloscope trace.
