Dual nature of light | Interference and its type

Interference fringes are obtained due to the interference of wave from two coherent sources of light with amplitudes a_(1) and a_(2)(a_(1)=2a_(2)) . The ratio of the maximum and minimum intensities of light in the interference pattern is

The dual nature of light is exhibited by
