Why is it recommended to allow the wave to reflect several times?
Why is it recommended to allow the wave to reflect several times?
- To measure the total distance travelled and time taken to obtain an average for a more accurate result (correct)
- To increase the amplitude of the wave for a more accurate calculation
- To change the frequency of the wave for a more accurate measurement
- To decrease the wavelength of the wave for a more precise outcome
How can the speed of the wave be calculated?
How can the speed of the wave be calculated?
- By measuring the time taken for the wave to travel and using the formula speed = distance ÷ time (correct)
- By observing the pattern of the wave and using the formula speed = wavelength ÷ frequency
- By counting the number of reflections and using the formula speed = distance × number of reflections
- By measuring the amplitude of the wave and using the formula speed = amplitude × time
