The photon has a momentum as well as a wavelength.
a) Which property of matter is revealed in the above statement? (1)
b) A photon has a mass of 8.6 x10-30 kg. Calculate its wavelength. (Planck’s constant = 6.626 x 10-34 Js

(a) It depicts that photon has Dual nature, that is, particle as well as wave nature.

(b) This can be calculated by de-Broglie's equation:

     λ=hmv    = 6.626×10-348.6×10-30×3×108    = 0.25×10-12 m
