The formula relating wave speed (c), wavelength (2), and frequency (f) is: c = x f Use the Swap-Flip-Cancel algebra strategy to reorganize this equation to solve for the wavelength (2). Then calculate the wavelength of a visible light photon that has a frequency f = 4.051014 Hertz. The speed of light, in units of meters per second, is c = 2.998108 m/sec. [Note the change in units for the speed of light from the previous problem, now cis in meters per second, rather than kilometers per second]. Since the Hertz unit is defined as "1/second", if you do your algegra correctly the final units will work out to be meters. 2 = meters Enter your answer in scientific notation, properly rounded off, by first typing the mantissa, then an "e", then the exponent of the power of ten in the new box that appears.
