Your boss asks you to compare two sound waves and determine which has a higher frequency. Wave A has a period o 4/100 second and Wave B has a period of 1/7 second. What would you tell your boss?
AWave A has the higher frequency. It's frequency is 4 Hz
BWave A has the higher frequency. It's frequency is 25 Hz
CWave B has the higher frequency. It's frequency is 42 Hz
DWave B has the higher frequency. It's frequency is 7 Hz
Wave A has a higher frequency and that frequency is 25 Hz. This can be determined by taking the time span and dividing it by the number of waves/second. 100 divided by 4 is 25. 7 divided by 1 is 7. 25 Hz is higher than 7 Hz.
