!Periodic motion is a type of motion where an object repeats the same pattern of movement over a certain period of time. This could include back and forth motion, circular motion, or any other type of repeated movement.
Frequency is the number of cycles or repetitions of a periodic motion that occur in one second. It is measured in units of hertz (Hz) and is directly related to the speed of the motion.
Frequency and wavelength are inversely related. This means that as frequency increases, wavelength decreases, and vice versa. The mathematical equation for this relationship is: frequency = speed/wavelength.
To calculate the frequency of a periodic motion, you need to know the speed of the motion and the wavelength. Using the equation frequency = speed/wavelength, simply plug in the values and solve for frequency.
Some common examples of periodic motion include the swinging of a pendulum, the rotation of the Earth around the sun, the vibration of a guitar string, and the bouncing of a ball. These motions all follow a repeated pattern and have a specific frequency and wavelength.
