What else can I help you with?
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. :)
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.
Inverse transformation of planck's constant 'h' is and dimensional formula of it?
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].
What happends to the OH- as the H plus increases?
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

What was Niels Bohr's formula?
(E) Photon=E2-E1= hv h=Plancks constant v=frequency
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
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

A photon has a frequency of 4.0 multiplied by 104 Hz?
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
What is the value of plancks constant?
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.
How are the energy and frequency of electronmagnetic radiation related?
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.

The de Broglie wavelength of an electron is 8.7 10-11 m The mass of an electron is 9.1 10-31 kg The velocity of this electron is ms?
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

What is the energy of a photon having a frequency of 410E 7 hz?
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.
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.
