5.FREQUENCY
please help me it is urgent please solve please it is urgent ​

Answer 1

Explanation:

1 Oscillation is the repetitive variation, typically in time, of some measure about a central value or between two or more different states. The term vibration is precisely used to describe mechanical oscillation

2 Amplitude is the magnitude of change in the oscillating variable with each oscillation within an oscillating system. For example, sound waves in air are oscillations in atmospheric pressure and their amplitudes are proportional to the change in pressure during one oscillation.

3The time period is the time taken by a complete cycle of the wave to pass a point,

4Length of a simple pendulum: It is defined as the distance between the point of suspension to the centre of the bob

5Frequency is the number of occurrences of a repeating event per unit of time. It is also referred to as temporal frequency, which emphasizes the contrast to spatial frequency and angular frequency. Frequency is measured in units of hertz which is equal to one occurrence of a repeating event per second

Answer 2

Answer:

I) to and fro motion of the object.

II) Amplitude is the magnitude of change in oscillating variable with each other oscillation within an oscillating system .

III) Time taken to complete one cycle of the wave.

IV) The difference between point of suspension to the center of bob.

V) Number of complete cycle of wave passing a point in a unit time.

Glad I could help you.

Thanks.
