The first flag of the United States of America had 13 stars, white  on a field of blue representing a new constellation.. The 13 stars  actually represented the first 13 stâ¦ates of our new nation in 1776.
#c = 3.00 x 10^8#m/s (the speed of light in a vacuum) #lambda# = wavelength in meters. #nu# = frequency in Hertz (Hz) or #1/s# or #s^-1#. So basically the wavelength times the frequency of an electromagnetic wave equals the speed of light. FYI, #lambda# is the Greek letter lambda , and #nu# is the Greek letter nu (it is not the same as a v). To find wavelength (#lambda#), the equation is manipulated so that #lambda = c/nu#. EXAMPLE PROBLEM.
It's easy! 1  Just use our wavelength calculator in the following way: 2  Determine the frequency of the wave. For example, f = 10 MHz. This frequency belongs to the radio waves spectrum. 3  Choose the velocity of the wave. As a default, our calculator uses a value of 299 792 458 m/s - the speed of light propagating in the air. Substitute these values into the wavelength equation Î» = v/f. Calculate the result - in this example, wavelength will be equal to 29.98 m. You can also use this tool as a frequency calculator.
