Tally Charts & Frequency Tables. 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.

Show step. As we already know the relative frequency, substitute this and the frequency of rolling a 4 4 into the formula. 0.2=\frac {32} {\text {number of times the die was rolled}} 0.2 = number of times the die was rolled32. Rearrange the formula. Number of times the dice was rolled =\frac {32} {0.2}=160 = 0.232 = 160.
Example 1: Find the frequency of a lightwave when the wavelength of the light is 2 meters. Solution: Given: Wavelength (λ) = 2 meters (m) To find: Frequency (f) Using Frequency formula: f = v λ. where v is the speed of light (approximately 3 × 10 8 meters per second (m s)) f = 3 × 10 8 m/s 2 m. f = 1.5 × 10 8 Hz.

Answer: Frequency is 2Hz. Example 2: Find the frequency of lightwave when the wavelength of the light is 600nm. Solution: To find: Frequency. Given: Wavelength = 600nm = 600 × 10 -9 m. = 6 × 10 -7 m. We know that the speed of the light = 3 × 10 8 m/s. Using frequency formula. f = 𝜈 / λ.
