Wave on a String 1.0.0 (pearsoncmg.com)

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 (which 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.

- varied
- decreases
- reflective
- amplitude
- remains relatively constant
- wavelength
- increases

1. Inside a laser apparatus, the stimulation and relaxation of electrons in atoms causes many photons with the same **wavelength** to be continuously emitted. When these photons are emitted, they travel between two **reflective** surfaces to form the wave that is represented in the simulation.

2. This wave is the summation of all the photons being introduced with every oscillation, and as they continue to travel, the amplitude **increases**. This occurs because the photons are emitted in coherent fashion (constructive interference); however, amplitude **decreases** when the photons overlap in an incoherent fashion (destructive interference).

3. In a laser device, a small portion of photons are permitted to escape (for use in an application). This is emulated in the simulation, where Damping represents the loss of photons. When Damping is set to Lots, the amplitude **decreases** compared to when Damping is set to None.

4. The generation of multiple wavelengths is possible in some laser producing systems, and the diffraction angle can be **varied** to allow the isolation of different wavelengths.

5. Finally, when the power of a laser is described, the wave property that is being referenced is a function of its frequency and **amplitude**.
