Which Of The Following Is The Unit Of Planck’s Constant?

What Is Planck’s Constant?

Planck’s Constant is a physical constant that is related to the energy of light. It was discovered by Max Planck in 1900, and is now an essential part of our understanding of quantum mechanics. This constant is the measure of the amount of energy that is released when a single particle of light, or a photon, is emitted.

What Is The Unit Of Planck’s Constant?

The unit of Planck’s Constant is the joule-second (J⋅s). This is a derived unit, meaning it is made up of two other units, the joule (J) and the second (s). The joule is a unit of energy, and the second is a unit of time. The joule-second is the product of these two units, and is used to measure the energy of a single particle of light.

How Is Planck’s Constant Used?

Planck’s Constant is used in many areas of physics, and is important for understanding the behavior of light, matter, and energy. It is used to calculate the energy of a photon, and is also used to calculate the energy of molecules and atoms. It is also used in quantum mechanics, as it is related to the Heisenberg Uncertainty Principle.

What Is The Value Of Planck’s Constant?

The value of Planck’s Constant is 6.626 × 10-34 J⋅s. This value is considered to be exact, and is accepted to be the same in all systems of measurement. This value is used in many calculations in physics, and is one of the most important constants in physics.

Conclusion

Planck’s Constant is a physical constant that is related to the energy of light. The unit of Planck’s Constant is the joule-second (J⋅s). This constant is used to calculate the energy of a photon, as well as the energy of molecules and atoms. The value of Planck’s Constant is 6.626 × 10-34 J⋅s.
