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 a wave is calculated using the formula: Wavelength = speed of the wave divided by the frequency of the wave. For radio waves and other wireless signals as w â¦ ell as the speed a signal travels along a wire, the speed of the wave is approximately 299,792,458 meters per second (the speed of light).he speed of a wave equals the frequency times the wavelength (speed = frequency x wavelength). Therefore, the wavelength would equal the speed divided by the frequency. Also, â¦ the speed of a wave in a vacuum is the speed of light, c, which is a constant.
