Physics: Waves: Units
Gbogbo ọrọ náà
Wave calculations require just five units, but getting them wrong can throw your answer out by a factor of a thousand. Wavelengths given in nanometres, frequencies in kilohertz, angles in degrees - each needs careful handling before it goes into an equation.
This reference covers the five units for the waves section of the Edexcel specification: degree, hertz, metre, metre per second and second.
Ebumnobi
- Use the following units: degree, hertz (Hz), metre (m), metre/second (m/s) and second (s)
