Physics - Waves - Properties - Wavelength, frequency, and amplitude - Wave Measurements
A 5-step lesson. Step 1: 'Amplitude (A): The maximum displacement from the rest position. Measured in meters. For sound: bigger amplitude = louder. For light: bigger amplitude = brighter.' Step 2: 'Wavelength (λ): The distance between two consecutive identical points (peak to peak, or trough to trou
