Why LED is used to determine planks constant?
led is used to determine Plancks constant
Is gas constant equal to planks constant?
No, gas constant is having a value of 8.314Jk-1mol-1 Whereas plancks constant has a value of 6.6*10-31
What was Niels Bohr's formula?
(E) Photon=E2-E1= hv h=Plancks constant v=frequency
What is the wavelength of an electron moving with a velocity of 2.5 x 108 cm s1?
Wavelength = Plancks constant / (Mass x Velocity)
What do you need to know to calculate the frequency of a wave?
wavelength since frequency =hc/lambda h=plancks constant and c=velocity of light
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.
Which dimensional formula contains speed of light plancks constant and gravity?
Such a melange of dimensions would involve length3 mass2/time4 .Not only has it no physical significance, but, fortunately for all of us,there is no such formula.
If the frequency of ultraviolet light is 2.53 x 10 power of -7 plancks constant is 6.63 x 10 power of -34 and the work function is 3.6eV what is the maximum kinetic energy?
you need units
What is the energy of a photon having a frequency of 410E 7 hz?
use the equation E = hf where h is plancks constant E = 410E 7 * 6.63E -34 E = 2.7183E -23 joules
What was Max Plancks biggest invention?
The Quantum Theory.
How are the energy and frequency of electronmagnetic radiation related?
We need to know the equation E=h where h=plancks constant . From this equation you can see that energy and frequency are directly related ( one increases as the other one dicrease )
If the energy of an electron is found with Energy equals hc divided by lamda which contains only positive terms how can the energy of a bound electron be negative?
The h in the hc stands for plancks constant which is 6.63 x10^-34, which is negative. :)
