  1. The frequency formula is used to find the frequency of a wave. Frequency is defined as the number of cycles completed per unit time. It also tells about how many crests go through a fixed point per unit time. Sometimes it is known as reciprocal of time. Frequency is expressed in Hertz (Hz).

  2. Frequency is the number of times a particular value occurs in a set of data. Usually we would record the frequency of data in a frequency table. Example: Using the key: H = Hockey, B = Badminton, F = Football, each letter below indicates a student joining the sports club. H H B F B H F F H B.

  4. Using Frequency formula: `f = \frac{1}{T}` `T = \frac{1}{f}` `T = \frac{1}{40}` `T = 0.025` Time period is `0.025` second. Example `5`: Find the frequency of a lightwave when the wavelength of the light is `200` nm. Solution: Given: Wavelength `(\lambda) =` \(200\, \text{nm}\) `=` \(200 \times 10^{-9} \, \text{m} \) `=` \(2 \times 10^{-7 ...
