To simulate the production of laser light, apply the following settings in the PhET simulation: Oscillate radio button; Fixed End radio button; Amplitude, 0.10 cm; Frequency, 1.26 Hz; Damping, none. Once you are certain that you have made all of the selections, click Restart and observe what occurs with the wave over the next twenty seconds. Then, keep all other settings the same while setting Frequency to 1.30 Hz and restart it again (this is an example of a failure to generate laser light). Use your observations to help you complete the following statements about the generation of a laser.
Match the words in the left column to the appropriate blanks in the sentences on the right. Make certain each sentence is complete before submitting your answer.

1. Inside a laser apparatus, the stimulation and relaxation of electrons in atoms causes many photons with the same to be continuously emitted.
2. When these photons are emitted, they travel between two surfaces to form the wave that is represented in the simulation.
3. This wave is the summation of all the photons being introduced with every oscillation, and as they continue to travel, the amplitude .
4. This occurs because the photons are emitted in coherent fashion; however, amplitude when the photons overlap in an incoherent fashion.
5. In a laser device, a small portion of photons are permitted to escape (for use in an application), which is emulated by setting the Damping to Lots such that the amplitude when compared to a Damping of None (damping represents the loss of photons).
6. The generation of multiple wavelengths is possible in some laser producing systems, and the diffraction angle can be to allow the isolation of different wavelengths.
7. Finally, when the power of a laser is described, the wave property that is being referenced is a function of its frequency and .

Use henry's law and the solubilities given below to calculate the total volume of nitrogen and oxygen gas that should bubble out of 1.7 l of water upon warming from 25 ˚c to 50 ˚c. assume that the water is initially saturated with nitrogen and oxygen gas at 25 ˚c and a total pressure of 1.0 atm. assume that the gas bubbles out at a temperature of 50 ˚c. the solubility of oxygen gas at 50 ˚c is 27.8 mg/l at an oxygen pressure of 1.00 atm. the solubility of nitrogen gas at 50 ˚c is 14.6 mg/l at a nitrogen pressure of 1.00 atm. assume that the air above the water contains an oxygen partial pressure of 0.21 atm and a nitrogen partial pressure of 0.78 atm.
