1 Travelling and Standing Waves Many biological phenomena are cyclic. Heartbeats Circadian rhythms, Estrus cycles Many more e.g.’s Such events are best described as waves. Therefore the study of waves is a major component of this biophysics course. Sound Waves: Study guide 2 (Acoustics, vibrating strings) Electromagnetic Waves: Study guide 3-4 (Light, X-rays, Infra-red) Quantum Mechanical Waves: Study guide 4-6 (motion of elementary particles/waves)

How to evaluate sin(x), cos(x), sin -1 (x), cos -1 (x) 2. Equations for travelling and standing waves 3. How to graph a wave given the equation 4. Relations between period (T), frequency (f or υ ) and wavelength ( λ ) Type of wave Form Sinusoidal y = Asin(x) Square y = A for 0 < x < λ /2, = -A for λ /2 x λ Ramp y = Cx, for - λ /2 x λ /2 Periodic functions can be described as a sum of sinusoidal waves. Therefore we need trigonometry
