Production and propagation of waves: WAEC Physics Past Questions and Answers

What the WAEC syllabus covers in Production and propagation of waves

Our summary: How waves start and travel, and how frequency, wavelength, period and speed are linked.

• Production and propagation of mechanical waves (Use of ropes and springs (slinky) to generate mechanical waves.)
• Pulsating system: energy transmitted with definite speed, frequency and wavelength (Use of ripple tank to show water waves and to demonstrate energy propagation by waves. Hertz (Hz) as unit of frequency.)
• Waveform (Description and graphical representation. Amplitude, wavelength, frequency and period. Sound and light as wave phenomena.)
• Mathematical relationship connecting frequency ($f$), wavelength ($\lambda$), period ($T$) and velocity ($v$) ($v = f\lambda$ and $T = 1/f$; simple problems may be set.)
