**If your digital multimeter offers a frequency setting (Hz is the symbol) on the dial:**

- Turn the dial to Hz.
- First insert the black test lead into the COM jack.
- Then insert the red lead into the V Ω jack.
- Connect the black test lead first, the red test lead second.
- Read the measurement in the display.

Correspondingly, what is the formula of frequency?

**f**= c /

**λ**=

**wave speed**c (m/s) /

**wavelength λ**(m). The formula for time is: T (period) = 1 /

**f**(frequency).

**λ**= c /

**f**=

**wave speed**c (m/s) / frequency

**f**(Hz). The unit hertz (Hz) was once called cps =

**cycles per second**.

What is the frequency in a wave?

Wavelength is also measured in metres (m) - it is a length after all. The

**frequency**, f, of a**wave**is the number of**waves**passing a point in a certain time. We normally use a time of one second, so this gives**frequency**the unit hertz (Hz), since one hertz is equal to one**wave**per second.What is frequency with example?

**Frequency**describes the number of waves that pass a fixed place in a given amount of time. The hertz measurement, abbreviated Hz, is the number of waves that pass by per second. For

**example**, an "A" note on a violin string vibrates at about 440 Hz (440 vibrations per second).
