        Postulates
        
        The radiant energy is emmited/absorbed in small energy packets called quantum. In case of light they are called photons
        
        Energy of each quantum proportional to frequwncy E = hv
        
        Total amount of energy emiited/absorbed - E = nhv
        
        Properties of photons
        
        Energy of single photon - E= hv
        
        Travel as waves but aborobed/wmitted as particles
        
        All phoyons travel with speec of light but speed changed in diff emdium however frequency remains same. Speed does not depend on energy
