Question

According to quantum theory, the energy E of a photon frequency f is given by E = hf, where h is planck's constant. What is dimensional formula for h?
(A) Mâ»Â¹L²Tâ»Â²
(B) M¹L²Tâ»Â¹
(C) M¹L²T¹
(D) M¹L²T²

Answer 1

Answer:

dimensional formula for h :  ML²T⁻¹

Explanation:

E = hf, where h is planck's constant.

E = Energy  Dimensional Formula

= ML²T⁻²

f = Frequency Dimensional Formula = T⁻¹

h = E/f   = ML²T⁻² / T⁻¹

ML²T⁻¹

dimensional formula for h ML²T⁻¹
