Frequency of photon = 2.10 x 1014
As we know,                    Speed of light = Wavlength x Frequency
                               So, Wavelength = Speed of light                                                                                                                                 Frequency
 
                                   Wavelength  = 3 x 108
                                                       2.1 x 1014
 
 
                                  Wavelength = 1.428 x 10-6 m
