| Question | Answer |
| Frequency is the inverse of the period | f = \(\frac{1}{T}\) |
| The wave equation | V = f \(\lambda\) |
| Intensity = | \(\frac{Power}{Area}\) |
| Intensity is | ∝ \((Amplitude)^2\) |
| Refractive Index = | \(\frac{Cmedium1}{Cmedium2}\) = \(\frac{sini}{sinr}\) |
| Refractive Index of material | n=\(\frac{Cvacuum}{Cmaterial}\) |
| Snell's Law | n1\(\sin\)\(\theta\)1 = n2\(\sin\)\(\theta\)2 |
| Line Separation = | \(\frac{1}{lines/metre}\) |
| Fringe Spacing | w = \(\frac{λD}{s}\) |
| Incident light wavelength | nλ = d\(\sin\)\(\theta\) |
| Standing Waves: String experiment Equation 1 | Mass/unit length: \(\mu\) = \(\frac{M}{L}\) |
| Equation 2 | Tension: T = mg |
| Equation 3 | Wavelength given as: \(\lambda\) = 2l |
| Equation 4 | Frequency: f = \(\frac{1}{2l}\)\(\sqrt {\frac{T}{μ}}\) |
| Equation 5 | v = \(\sqrt {\frac{T}{μ}}\) |
