WAVE MODEL

1. EMR is a transverse sinusoidal wave.
2. Frequency is measured in Hertz (Hz) where 1 Hz = 1 oscillation per second.
3. Waves have successive peaks and troughs, the distance between 2 peaks is known the wavelength (λ).
4. The height of the peak is the amplitude (A).
5. The time between 2 peaks is the period (T).
6. The wave has a velocity (v).
7. As waves cross boundaries between different media, their velocity changes (hence, wavelength, as stated by the wave equation) but the frequency stays the same.
