Q15 of 44 Page 7

Photon is quantum of radiation with energy E = hν where ν is frequency and h is Planck’s constant. The dimensions of h are the same as that of

According to plank, the energy of photon is given by the expression,



Where,


f= frequency of light


h= Planck’s constant



Dimension of E=


Dimension of f=


So, dimension of h,



Now,


Linear impulse=forcetime




Angular impulse= torque time


=


=


Linear momentum= mass velocity


=


=


Angular momentum= moment of inertia angular velocity


=


=
