Answer 1

1) If a cycle begins at a certain position, it ends when the object next returns to this position while traveling in the same direction.

2) A bob oscillates on a vertical spring. If the frequency of the motion is two cycles per second, the period is 1/f = 1/2 seconds

that is one-half second.

3) As you increase the frequency of putting your finger into water, the wavelength of the water waves decreases. The speed of the waves remains the same, hence the product of frequency and wavelength should not change. so if frequency increases, then wavelength must decrease.

4) .For small amplitudes, the period for the motion of an object on a spring is inversely proportional to the square root of the value of the spring constant
