A simple equation relates wavelength to frequency: v = λf 1. v = wave velocity (how fast the wave propagates in a medium) 2. λ = wavelength (distance over which a wave shape repeats) 3. f = wave frequency (number of waves per unit of time) For light and other electromagnetic radiation in a vacuum, the wave velocity is the speed of light(c): c = λf ...
Rearrange the equation and calculate wavelength from frequency: λ = v/f For example, find the wavelength of the musical note A4, which has a frequency of 440 Hz. The only tricky part in the calculation is keeping the units straight. Usually, you work with meters and Hertz and then convert to other units (e.g., nanometers, THz, GHz). In this problem...
Rearrange the equation and calculate frequency from wavelength: f = v/λ For example, find the wavelength of orange light with a frequency of 4.8×1014Hz. f = v/λ (but v is c for light) f = c/λ f = (3.00 × 108 m/s)/(4.8×1014 s-1) f = 6.2 x 10-7m = 620 nm

Example 1 The table below shows the times taken by a group of walkers to complete a 15-mile walk. Their times have been recorded to the nearest hour. Illustrate the data using a bar chart and a frequency polygon. Solution A time of 5 hours actually means a time that is greater than or equal ...

Example. Make a frequency distribution for the following data, using 5 classes: 5 10 7 19 25 12 15 7 6 8. 17 17 22 21 7 7 24 5 6 5. The smallest number is 5, and the largest is 25, so the range is 20. The class width will be 20=5 = 4, but we need to round up, so we will use 5. Our classes will be 5{9, 10{14, 15{19, 20{24, and 25{29.
