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.
As stated wavelength and frequency have an inverse relationship which means that if frequency goes up wavelength will go down, and if wavelength goes us frequency will go down and visa versa. To calculate wavelength we would rearrange the equation to . Wavelength = C / Frequency . and to calculate frequency we rearrange the equation to . Frequency = C / Wavelength
