Frequency of oscillations is the no. of oscillations of a vibrating object per second . therefore frequency is =40 vibrations /4 sec=10 hertz time period is the time required to complete 1 oscillation. or it is the inverse of time period . time period is= 1/10=0.1 second
Answers & Comments
Frequency = 40÷4
Frequency = 10 Hertz .
time period of one oscillation is equal to 1÷ frequency
time period = 1÷ 10
time period = 0.1 second.
therefore frequency is =40 vibrations /4 sec=10 hertz
time period is the time required to complete 1 oscillation. or it is the inverse of time period .
time period is= 1/10=0.1 second
