1. Calculate the frequency, in Hz, for the red spectral line of hydrogen with a wavelength of 656 nm. (3 s.f.) 2. Determine the value of 1/λ, with λ in meters, for the red spectral line above (yes, it is that easy – 1 divided by lambda. Be careful of the conversion to m–1unit). 3. The Rydberg equation can be thought of as 1/l= (Ryd)(transition value). Determine the “transition value” from n = 4 to n =2. (Don’t determine the energy, nor the wavelength,...

They can jump up to higher orbits or down to lower orbits. Emitted Spectral lines: When electrons in the higher orbits (with higher energies) jump DOWN to Lower orbits (with lower energies), energies are emitted in the form of emitted photons (light). The electrons jump from n = 7 state...

Problem (8 points) For the Photoelectric Effect experiment shown, when ultraviolet light with a wavelength of 240 nm shines on a particular metal plate, electrons are emitted from plate 1, crossing the gap to plate 2 and causing a current to flow through the wire connecting the two plates. The battery voltage is gradually increased until the current in the ammeter drops to zero, at which point the battery voltage is 1.40 V plate 2 AV incident ◇e electrons Tammeter...

When an electron of an excited hydrogen atom descends, from an initial energy level (ni) to a lower (nf), characteristic electromagnetic radiation is emitted. The Bohr model of the H-atom allows the calculation of ?E for any pair of energy levels. ?E is related to the wavelength (?) of the radiation according to Einstein's equation ( ?E = [(hc)/?]). Distinct series of spectral lines have been classified according to nf: Lyman series:nf=1 (91<?<123 nm; near-UV). Balmer series:nf=2 (365<?<658 nm; visible)....
