8.00 x 10 2 Hz . The period is the time for one complete cycle. If the pendulum takes 20.0 seconds for exactly 40 vibrational cycles, then it must take 0.500 second for one cycle.
How do you find the frequency of a pendulum?
Calculate the period of oscillations according to the formula above: T = 2π√(L/g) = 2π * √(2/9.80665) = 2.837 s . Find the frequency as the reciprocal of the period: f = 1/T = 0.352 Hz . You can also let this simple pendulum calculator perform all calculations for you!
What is the period of oscillation of a pendulum with 20 oscillations in 40 seconds?
Answer: The time period taken by the pendulum is 2 seconds . I hope answer is helpful to you.
What is the frequency of oscillation if the time period is 40 ms?
Frequency is defined as the number of oscillations per unit time. Time = 4 sec. Time Period = (4/40) = 0.1 sec. Frequency = (Number of Oscillations)/ (Time taken)Frequency = (40/4) = 10Hz .
What is the time period of a pendulum which takes 20 s for 10 oscillation?
When a simple pendulum makes 10 oscillations in 20 seconds, the time taken for each oscillation = 20/10 = 2 seconds . Hence, as the time period is calculated to be 2 seconds, the frequency of oscillation = 1/T = 1/ 2 = 0.5 Hertz.
What affects the frequency of a pendulum?
Explanation: The only two factors that affect a pendulum’s frequency are the acceleration due to gravity (g) and the length of the pendulum’s string (L) .
Does mass affect frequency of a pendulum?
Mass of the bob at the end of the pendulum-Changing the mass of the pendulum bob does not affect the frequency of the pendulum . ... The momentum built up by the acceleration of gravity causes the mass to swing in the opposite direction to a height equal to the original position.)
What is the time period for a pendulum?
The time taken to complete one oscillation is known as the time period of the pendulum. Given: – 20 oscillations taking 32s to complete. Therefore 1.6s is the time period of the pendulum.
What is one oscillation of a pendulum?
One oscillation is completed by a pendulum when it starts from the extreme position A and moves to the other extreme position B and then returns to A. The time to complete one oscillation is called the time period . The time period of oscillation remains constant.
What is time period formula?
Time Period (T) = 2× π × √(L/g) Or, T = √[M 0 L 1 T 0 ] × [M 0 L 1 T – 2 ] – 1 = √[T 2 ] = [M 0 L 0 T 1 ]. Therefore, the time period is dimensionally represented as [M 0 L 0 T 1 ].
What is relation between frequency and time period?
Sound | Short/Long Answer Questions
The number of times a cycle is completed in a second is the frequency. The time taken to complete one vibration is called time period. Frequency and time period is inversely proportional , the number of vibrations per second is frequency.
Is time a frequency?
Frequency is a rate quantity . Period is a time quantity. Frequency is the cycles/second. Period is the seconds/cycle.
What is the formula of oscillation?

What is the time taken by the pendulum to make 10 oscillations?
Answer:When a simple pendulum makes 10 oscillations in 20 seconds, the time taken for each oscillation = 20/10 = 2 seconds . As the time period is calculated to be 2 seconds, the frequency of oscillation = 1/T = 1/ 2 = 0.5 Hertz.
What is the time period of a pendulum which is oscillating 10 times in one second?
So, it reaches extreme position twice in one oscillation. Hence the time period of second’s pendulum is 2 seconds . So, the correct answer is option (B). The frequency of a second’s pendulum is 0.5 Hz.
What is the relation between the length of the pendulum and its frequency?
A pendulum with a longer string has a lower frequency, meaning it swings back and forth less times in a given amount of time than a pendulum with a shorter string length.
