Photon is a quantum of radiation with energy E = hv where v is the frequency and h is Planck’s constant. The dimensions of h are the same as that of:
a) linear impulse
b) angular impulse
c) linear momentum
d) angular momentum
The answer is the option (b) Angular Impulse and (d) Angular momentum
Explanation: It is given that E = hv
Hence, h (Planck’s constant)
Now, Linear Impulse = F.t
& Angular Impulse =
Now, Linear momentum = mv
& Angular momentum (L) = mvr
Thus, the dimensional formulae of Planck’s constant, Angular Impulse and Angular Momentum are the same.
