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.
Electromagnetic waves travel at the speed of light (299,792,458 meters per second) and their frequency and wavelength can be determined by the formulas: where 'c' is the speed of light in meters per second, the Greek letter lambda Î» is the wavelength in meters and the frequency is in cycles per second. is in meters. As always, we have written a calculator to make the work a little easier for you. This calculator was extensively rewritten on October, 2011.
