Lesson outcome
I can explain how to make measurements of distance and time to accurately measure the speed of water waves.
Show transcript
The speed of water waves can be measured using measurements of distance travelled and time taken.
Random errors are made when the method limits how accurate a measurement can be.
The effect of random errors can be reduced by repeating readings and calculating a mean.
The uncertainty in a mean result is calculated from half the range of the repeat measurements.
