Waves (Edexcel GCSE Physics Combined Science): Flashcards

Energy

No, only energy. Particles vibrate but don't move along.

Perpendicular to wave direction

Electromagnetic waves, S-waves, water ripples

Parallel to wave direction

Sound waves, P-waves

Compressions and rarefactions

Maximum displacement from rest position

Distance between corresponding points on adjacent waves

Number of complete cycles per second

Hertz (Hz); 1 Hz = 1 wave per second

$\text{Period} = \frac{1}{\text{Frequency}}$

$\text{Wave Speed} = \text{Frequency} \times \text{Wavelength}$
