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 formula for the Wave Frequency is: f = $\frac{Number\ of\ Oscillation}{Time\ taken}$ The inverse or the reciprocal of the time period is the frequency of the wave. The frequency is the quantity obtained when we divide velocity of the wave by its wavelength.f = $\frac{1}{T}$ where T = time period.The figure depicts the different types of waves as classified according to their frequencies.he frequency is the quantity obtained when we divide velocity of the wave by its wavelength. f = $\frac{1}{T}$ where T = time period.
