1. Careful spectral analysis shows that the familiar yellow light of sodium lamps (such as street lamps) is made up of photons of two wavelengths, 589.0 nm and 589.6 nm. What is the differene in energy (in joules) between photons with these wavelengths?
2. What is the de Broglie wavelength, in cm, of a 12.4-g hummingbird flying at 1.20x mph? (1 mile = 1.61km.)
3. An ion derived from a metal in the first transition metal series has four electrons in the 3rd subshell. What element might be M?
4. Which or the following species are isoelectronic with each other?© BrainMass Inc. brainmass.com March 4, 2021, 9:24 pm ad1c9bdddf
This solution describes how to convert wavelength of light to energy, how to find the de Broglie wavelength of a moving object, how to identify an element based on electronic structure and how to identify isoelectronic species.
