What is the SI unit of radiation constant?

In the SI system the radiation constant (Stefan-Boltzmann constant) is measured in W/m2.K4.


Why LED is used to determine planks constant?

LEDs (Light Emitting Diodes) are used in determining the Planck constant because they emit light at specific frequencies when electrical current is applied. By measuring the voltage needed to produce light of a known frequency, the relationship between energy and frequency can be studied, allowing for the accurate determination of the Planck constant.

What the si unit of force and gravitation?

The SI unit of force is the newton (N) and the SI unit of gravitation is the newton also.


What is the base unit of Plancks constant?

Planck's constant relates the energy level of radiation due to electrons moving from one energy level to another, by the formula Energy = (Planck's constant) x (frequency of radiation). Therefore the dimensions of Planck's constant are (energy)/(frequency) which means Joules x seconds In fact Planck's constant = 6.67 x 10-34 joule.seconds.
