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.
These vibrations are measured in wavelength and frequency. The wavelength of a vibration is the distance over which a wave repeats, so the greater the wavelength, the greater the energy.ou can just use frequency to calculate energy E=hf  where E=energy h=planck's constant=6.626Ã10â34 J/s f= frequency   But if you are given the wavelength, you migh â¦ t need this:  since v= Î» x f  where v=speed Î»=wavelength f=frequency and v=c= speed of light=3x108m/s  Hence, E= hf= h(cÃ·Î»).
