Description

A 4-step lesson. Step 1: 'The wave equation: v = fλ. Speed (m/s) = Frequency (Hz) × Wavelength (m). This applies to ALL waves: sound, light, water, everything.' Step 2: 'Understanding the equation: In one second, f waves pass a point. Each is λ long. So the distance covered in 1 second = f × λ = spe
