For your work in a mass spectrometry lab, you are investigating the absorption spectrum of one-electron ions. To maintain the atoms in an ionized state, you hold them at low density in an ion trap, a device that uses a configuration of electric fields to confine ions. The majority of the ions are in their ground state, so that is the initial state for the absorption transitions that you observe. (a) If the longest wavelength that you observe in the absorption spectrum is 13.56 nm, what is the atomic number Z for the ions? (b) What is the next shorter wavelength that the ions will absorb? (c) When one of the ions absorbs a photon of wavelength 6.78 nm, a free electron is produced. What is the kinetic energy (in electron volts) of the electron?

The threshold of dark-adapted (scotopic) vision is 4.5 ✕ 10−11 W/m2 at a central wavelength of 500 nm. If light with this intensity and wavelength enters the eye when the pupil is open to its maximum diameter of 7.9 mm, how many photons per second enter the eye?
Question 2: Deduce the work function for sodium from Fig. Q2. The intersection of the straight line with the horizontal axis is the cutoff frequency, vo=5.8×1014 /sec. For most conducting metals the value of the work function is of the order of a few electron volts. Calculate the photon energy of a typical microwave wavelength of λ = 5 cm. Can this energy sufficient to eject photoelectrons from metal surfaces? Why? Stopping potential (V) 3 2 0 VO 8 12 4 Frequency (1014/sec) Fig. Q2

What is the energy in eV and wavelength in µm of a photon that, when absorbed by a hydrogen atom, could cause a transition from the n = 4 to the n = 6 energy level? (a) energy in eV? (b) wavelength in µm?
A light wave of a particular frequency hits a metal. The light wave is made of discrete photons, each with energy hf = hc/λ. An electron will either completely absorb a photon, or not at all. An electron in a metal needs an energy to leave the metal -- the work function (W). For the W given, calculate the maximum light wavelength (in nm) that will eject an electron. I will use electron-volts (eV) for energy, because the computer gives me trouble with very low numbers. hc = 1240 eV nm W = 3.9 eV

What is the wavelength in meters of a photon generated by an electron going from n = (8.000x10^0) to n= (1.00x10^0)? Answer to 3 significant figures and in scientific notation. Sorry about the two n values, I can either do scientific notation need for the answer or you have to enter the answer without scientific notation. I can't change between them. Note: Your answer is assumed to be reduced to the highest power possible. Your Answer: Answer x10 units
