The definition of quantum number.

Explanation of Solution
A number which labels possible values of conserved physical quantities like momentum or energy is known as quantum number. For any system , thepossible quantum states of the system are labled by the quantum number.
Forexample, for hydrogen atom the quantum numbers are principal quantum
Which quantum number apply is determined by solving the Schrodinger equation and applying appropiate boundary conditios, which typicaslly restrict the possible solutions to those with specific values for various quantum number labeling the solutions.

- A spectra is a graph that has amplitude on the Y-axis and frequency on the X-axis. A harmonic spectra simply draws a vertical line at each frequency that a harmonic would be produced. The height of the line indicates the amplitude at which that harmonic would be produced. If the Fo of a sound is 125 Hz, please sketch a spectra (amplitude on the Y axis, frequency on the X axis) of the harmonic series up to the 4th harmonic. Include actual values on Y and X axis.arrow_forwardSketch a sign wave depicting 3 seconds of wave activity for a 5 Hz tone.arrow_forwardSketch a sine wave depicting 3 seconds of wave activity for a 5 Hz tone.arrow_forward
- The drawing shows two long, straight wires that are suspended from the ceiling. The mass per unit length of each wire is 0.050 kg/m. Each of the four strings suspending the wires has a length of 1.2 m. When the wires carry identical currents in opposite directions, the angle between the strings holding the two wires is 20°.
