Question
Chapter 28, Problem 23Q
To determine
The difference and similarity between ordinary light and laser light.
Expert Solution & Answer

Answer to Problem 23Q
Solution:
Difference | |
Ordinary light contains many wavelengths from red to violet and the combination is a white light. | Laser light is made up of one particular wavelength only and hence exhibit the color of that wavelength only |
Explanation of Solution
Similarity |
Both are energy carrying waves |
Ordinary light is produced by blackbodies at high temperatures by emitting a range of frequencies to cool down. On the other hand, laser light is produced by the transition of electron from higher energy state to lower energy state by exciting it using a particular frequency of photon.

- 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.
