If two emission lines in two different species have the same central frequency v0 and the same emission line width (FWHM, v ), but one is homogeneously broadened and the other is inhomogeneously broadened. Calculate the ratio of the intensities of these two line at a frequency displaced from the central frequency by 5v . Assuming the total intensities of both the lines are equal.

Two different simple harmonic oscillators have the same natural frequency (f=2.00 Hz) when they are on the surface of the Earth. The first oscillator is a pendulum, the second is a vertical spring and mass. If both systems are moved to the surface of the moon (g=1.67 m/s2), what is the new frequency of the vertical spring and mass?

There are two absorption lines in the spectral interval: One is located at 7283.02 cm-1 with a line strength of 1.132x10-2 cm-1/(atm cm) and a half width of 0.068 cm-1 (due to pressure broadening) at P0 = 1000 hPa, and another is located at 7283.73 cm-1 with a line strength of 1.71x10-2 cm-1/(atm cm) and a half width of 0.071 cm-1 at the same pressure. Calculate absorption coefficients at 7283.38 cm-1 for pressures of 1000 hPa and 500 hPa. Please...

Two tuning forks that have the same amplitude but slightly different frequencies are stuck at the same time to produce a complex wave. What is this called? If the period of the complex wave that they produce is 0.25s and the period of one of the tuning fork is 0.04s. What is one possible frequency of the other tuning fork? When the sinusoidal waves from the tuning fork are opposite phases, what happens at those points to the complex wave...

PART A Two light waves of the same frequency start out in phase (with amplitudes going up at the same moment), and they interfere having traveled different distances.  What happens if the path difference in the two waves is 1200 nm and the wavelength of the light is 400 nm (blue light)? The waves add in step and the  time-averaged power at that place is 4x that of one wave alone. The waves add in step and the  time-averaged power at that is...

Mastery Problem: CVP Analysis - Constructing a Cost-Volume-Profit Chart CVP Analysis and the Contribution Margin Income Statement For planning and control purposes, managers have a powerful tool known as cost-volume-profit (CVP) analysis. CVP analysis shows how revenues, expenses, and profits behave as volume changes, which helps identify problems and create solutions. In CVP analysis, costs are classified according to behavior: variable or fixed, rather than by category: product (which includes both variable and fixed) or period (which includes both variable...
