### Class subject: Frequency.

 Frequency is the number of occurrences of a repeating event per unit of time. It is also occasionally referred to as temporal frequency to emphasize the contrast to spatial frequency, and ordinary frequency to emphasize the contrast to angular frequency. For cyclical phenomena such as oscillations, waves, or for examples of simple harmonic motion, the term frequency is defined as the number of cycles or vibrations per unit of time. The conventional symbol for frequency is f.

This fun physics game may answer the following questions:
• Which is the object with the highest frequency?
• Which is the object with the lowest frequency?
• What is the frequency difference of objects?
