Write the frequency range What is the frequency of the object that Vibrates 120 times in 1 minute? |
|
Answer» if the object vibrates 30 times in 2 min, then it vibrates 15 times in 1 min.Then we divide 15 by 60(seconds), which GIVES us 0.25, and this is our frequency.Obs: We divide 15 by 60 because frequency means how many PERIODS in ONE second, and 1 minute have 60 seconds, and then, that’s why we divide by 60.Similarly, if you want to know the period, you divide 1/frequency , because frequency is the inverse of period, which gives us 4, and this means that 1 VIBRATION takes 4 seconds. |
