Meaning
Frequency is the number of waves that pass by in one second.
About Frequency
| Water Waves |
 |
| The frequency of this wave can be found by counting the number of times the red marker oscillates every second. |
- The higher the frequency the quicker the wave oscillates.
- In sound frequency is known as pitch. A high pitch is a high frequency.
- In light frequency affects the colour of the light. Red is a low frequency and violet is a high frequency.
Equation
\(f = \tfrac{1}{T}\) Where:
- f = frequency
- T = time period (the time it takes for a wave to pass a point).
