Waves & the EM Spectrum

12 min read

Wave properties, the wave equation, the electromagnetic spectrum, and reflection and refraction.

Waves transfer energy without transferring matter.

Wave properties

Transverse waves vibrate perpendicular to travel (light); longitudinal parallel (sound). $v = f\lambda \qquad T = \frac{1}{f}$

Worked example. A wave of $50$ Hz and wavelength $4$ m has speed $v = f\lambda = 200$ m s⁻¹.
