I've never seen this stated, so this is a guess: probably from harmonisch (German for "harmonic"), since Planck was attempting to develop equations of motion for light by treating it as a set of harmonic oscillators.
The h in the hc stands for plancks constant which is 6.63 x10^-34, which is negative. :)
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.
The inverse transformation of Planck's constant 'h' is called the reduced Planck constant, denoted as 'h-bar' or ħ, and it is equal to h divided by 2π. The dimensional formula of h is energy multiplied by time, or [ML^2T^-1].
The concentration of OH- decreases as the concentration of H+ increases. This is beacause there is an equilibrium H2O <-> H+ + OH- and therefore the [H+][OH-] is a constant

(E) Photon=E2-E1= hv h=Plancks constant v=frequency
wavelength since frequency =hc/lambda h=plancks constant and c=velocity of light
No, gas constant is having a value of 8.314Jk-1mol-1 Whereas plancks constant has a value of 6.6*10-31
The h in the hc stands for plancks constant which is 6.63 x10^-34, which is negative. :)
I assume the equation you're looking for is E=hv or E=hc/lambda. h is plancks constant and c is speed of light in m/s. lambda is in metres
The value of Planck's constant is approximately 6.626 x 10^-34 m^2 kg / s. It is a fundamental physical constant that relates the energy of a photon to its frequency.
The energy of electromagnetic radiation is directly proportional to its frequency. This relationship is described by Planck's equation: E = hν, where E is the energy, h is Planck's constant, and ν is the frequency. This means that as the frequency of electromagnetic radiation increases, so does its energy.

wavelength = h/p (h= Plancks constant = 6.636*10^-34 kg*m^2/s) p=m*v Combining these gives us v=h/(m*wavelength)=8.37*10^6 m/s

The energy of a photon can be calculated using the formula E = h*f, where E is energy, h is Planck's constant (6.626 x 10^-34 J.s), and f is frequency. Plugging in the values, the energy of a photon with a frequency of 4.1 x 10^7 Hz would be approximately 2.72 x 10^-26 Joules.
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.
