Question

Obtain the dimensions of Planck's constant.

Answer 1

Answer:

We know from the fundamental equation of Energy of a photon,

Energy= hn

where, h is the Planck's constant and n Is the frequency of the light wave.

So,

Dimensions of h = Dimension of Energy / Dimension of frequency

= ML^2T^-2 / T^-1

= ML^2 T^-1

This is the dimension of Planck's constant.

Hope this helps you !
