Question

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

Answer 1

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 .
