A) light consists of waves
B) light consists of particles
C) light is neither of particles nor waves
D) light consists of particles and waves both
Correct Answer: A
Solution :
Youngs double slit experiment was based on the hypothesis that, if light were wave like in nature, then it should behave in a manner similar to ripples or waves on a pond of water where two opposing water waves meet. They should react in a specific manner to either reinforce or destroy each other. If the waves are in step, then they should combine to make a larger wave. Hence, Youngs experiment established that light consists of wave while Plancks hypothesis gives detail of particle nature of light.
