Question

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

Answer 1

Explanation:

plz mark it the brainlliest

Answer 2

Answer :

We know that, E = hv.

Where, E is the energy, h is the Planck's constant and v is the frequency.

Now, h = E/v.

⇒ h = [M¹L²T^{-2}]/[T^{-1}]

⇒ h = [M¹L²T^{-1}]

Hence, the Dimensional Formula for Planck's constant is : [M¹L²T^{-1}].

The Dimensional Formula of Planck's constant is same as :

• Angular momentum
• Angular Impulse

Dimensions of physical quantities -

The dimensions of a physical quantity are the powers to which the base quantities are raised to represent that quantity.

Length : [L]

Mass : [M]

Time : [T]

Amount of substance: [A]

Thermodynamic temperature : [K]

Luminous intensity : [cd]

Amount of substance : [mol]
