What is the wavelength of visible light of 6 x 1014 hz frequency?

Wavelength of any wave = (speed of the wave) / (frequency)

Speed of light = approx 3 x 10⁸ m/s

                     Wavelength = (3 x 10⁸ m/s) / (6 x 10¹⁴ / sec)

                                         =  (3/6 x 10⁸ ⁻ ¹⁴)  ( m )

                                         =    0.5 x 10⁻⁶ meter  =  0.0005 millimeter .

Arise 8 run 1 this means go 8 up and 1 across, which is steepest

My answer is opptionc, just check with anyone else
