what is Plank's constant?

Question

numeric value

Answer 1

6.626 * 10^-34 J/Hz

Answer 2

Planck's constant (denoted h) is a physical constant that is used to describe the sizes of quanta.

It plays a central role in the theory of quantum mechanics

It is named after Max Planck, one of the founders of quantum theory.

Planck's constant is also used in measuring energy emitted by light photons, such as in the equation E=hν, where E is energy, h is Planck's constant, and ν (Greek letter nu) is frequency.

The value of Planck's constant is:

h=6.626 0693(11) x 10 ^ -34 j.s
=4.135 663 43(35) x 10 ^ -15 eV.s

Answer 3

It is the constant used in quantum theory. It is discovered and named after by the well known scientist max plank. It is used to calculate the quanta or energy packets of light. It is denoted by the letter "h"
The value of Planck's constant is:
h=6.6260693(11)*10-34 j/s

Answer 4

there is not any such element as Planck's concept, yet Planck's regulation states that each physique be counted which has temperature provides off a blackbody radiation in the eletromagnetic spectrum. Planck's Quantum hypothesis states that the potential of any molecular vibration must be an entire style dissimilar of hf, or incredibly E=nhf, the place h is the plancks consistent, f is frequency, and n=a million,2,3.... this incredibly stated the concept potential is quantized, and could in basic terms exist in discrete quantities. Planck's consistent is in elementary terms a persevering with which has dissimilar makes use of in Quantum mechanics. the cost is 6.626 x 10^-34 Js

Answer 5

Planck's constant (denoted h) is a physical constant that is used to describe the sizes of quanta. It plays a central role in the theory of quantum mechanics, and is named after Max Planck, one of the founders of quantum theory.

The value of Planck's constant is:

h = 6.626 0693(11) x 10^ -34 J.s

h = 4.135 667 43(35) x 10^ -15 eV.s

Answer 6

Planck's constant (denoted h) is a physical constant that is used to describe the sizes of quanta. It plays a central role in the theory of quantum mechanics, and is named after Max Planck, one of the founders of quantum theory. A closely-related quantity is the reduced Planck constant (also known as Dirac's constant and denoted , pronounced "h-bar"). Planck's constant is also used in measuring energy emitted by light photons, such as in the equation E=hν, where E is energy, h is Planck's constant, and ν (Greek letter nu) is frequency.

Planck's constant and the reduced Planck's constant are used to describe quantization, a phenomenon occurring in subatomic particles such as electrons and photons in which certain physical properties occur in fixed amounts rather than assuming a continuous range of possible values.

Answer 7

planck's constant relies the frequency of an electromagnetic wave to its energy

formula E=h* frequency

where h = 6.63 10^-34 Js
frequency in Hertz
E in joules
