Question

Write down the dimensions of plank's constant.

Answer 1

Energy = (plank's constant ) Frequency
plank's constant = Energy / Frequency
= [ ML^2 T^-2] / [T^-1]
=[ML^2 T^-1]

Answer 2

The dimensions of plank's constant is

plank's constant = energy / frequency

=[ M L^2 T ^-2] / [T^-1]

= [ M L^2 T ^-1]
