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.
The wavelength of an electromagnetic wave is its frequency divided into the speed of light which, for general purposes, is usually reckoned to be 3.0 x 10^8 meters per second. â¦ For example, at 100 megahertz, the wavelength equals 3 meters because: 300,000,000 / 100,000,000 = 3. 1 person found this useful.
