Question
Chapter 9, Problem 9.7QAP
Interpretation Introduction
Interpretation:
The reason for an emission line of the hollow-cathode lamp for molybdenum to develop a cuplike crater at its maximum at higher current needs to be explained.
Concept introduction:
Spectral lines are lines which help in identifying the atoms and molecules. These are a result of absorption or emission of light in a comparatively narrower frequency range compared to the frequencies nearby.
Until the lamp current is less than 50 mA for a hollow cathode lamp for molybdenum, the emission spectrum is a sharp line at 313.3 nm.

At a wavelength of 540 nm, the absorbance of the standard was 0.214 in a 1.00 cm cuvette. A 0.128 g sample of an iron ore was crushed and digested in 5 mL of concentrated acid. The digested sample was then transferred to a 10.00 mL volumetric flask and diluted to the mark with water. A 1.00 mL aliquot of the sample was transferred to a 25.00 mL volumetric flask, and diluted to the mark with water. A portion of the diluted sample was then transferred to a 1.00 cm cuvette and measured at a wavelength of 540 nm. The resulting absorbance was 0.216.

- Semiconductor materials are the basis of modern electronics Conduction band (e.g. the transistors, memory and camera in your cell phones). Common semiconductor materials include Si, GaAs and CdSe. The energy states of semiconductors are generally divided into the valence band, where the electrons are bound to the atoms, 2S(e) 1D(e) and the conduction band where the wavefunction solutions of 1P(e) electrons allow some of them (the excited electrons) to move through the bulk material. The energy difference between the maximum energy level of the valence band, termed the valence band maximum (VBM), and the lowest energy of the conduction band, termed the conduction band minimum (CBM), of bulk CdSe is 1.74 eV. As shown in the figure, this difference is known as the bandgap energy, Eg. The CBM can be regarded as the excited state while the VBM can be regarded as the ground state.
