WebbAccording to the Bohr model, the wavelength of the light emitted by a hydrogen atom when the electron falls from a high energy (n = 4) orbit into a lower energy (n = 2) … WebbWe can start with our equation that relates frequency, wavelength, and the speed of light. c=\lambda \nu c = λν. Next, we rearrange the equation to solve for wavelength. \lambda=\dfrac {c} {\nu} λ = ν c. Lastly, we …

WebbHowever you can get an approximate equation for the energy and wavelength by noting that the de Broglie wavelength is given by: $$ \lambda = \frac{h}{p} $$ For a non relativistic electron we have: $$ E = \frac{p^2}{2m} $$ Giving us: $$ E = \frac{h^2}{2m\lambda^2} $$ WebbFind the wavelength of the electrons. First I use E_k = 1/2mv 2 to find v. I get v = 18755375.5 m/s . Then I multiply v with m_e to get p. I get p to 1.70849898610-23. Then I use lambda = h/p . This gives me lambda = 3.87829832710-11. However in the answer key says that it should be 0.1 nm. How is this possible. elementis share price uk
