Frequency is the number of cycles per second represented in Hertz (Hz). The wavelength is the measure of the length of the wave (measured from peak to peak most commonly). In optics, wavelength determines the color of light, where frequency places it where it belongs in the electro-magnetic spectrum (i.e. infrared, ultraviolet, or visible to human eye).

What is difference between frequency polygon and line graph?
The difference between frequency polygon and line graphs is their purpose. Frequency polygons are for understanding shapes distributions, while line graphs shows information that is related in some way.
What is the Difference in relative frequency and percentage frequency?
Relative frequency is a method of calculating the frequency of an event. Percentage frequency is a way of presenting the frequency of an event.
How are the pieces of a pie chart related to relative frequency?
The pieces of a pie chart represent the parts of a whole, as does relative frequency. The total of the entire pie chart should be 100% or 360 degrees. The sum of the relative frequencies should also equal 100%.
What is the equation for frequency density?
frequency density = frequency/group width
Suppose that a frequency histogram and a cumulative frequency histogram are constructed from the same set of data using the same classes is the frequency for each class is the frequency equal to the?
the frequency is less than OR EQUAL TO the cumulative frequency
