Concept explainers
To explain:The procedure to use a light of known wavelength for obtaining the distance between two narrow slits.
Answer to Problem 33A
The
Explanation of Solution
Introduction:
The double slit experiment is used to show that the light and matter can exhibit both the particle and wave characteristics. The double slit experiment can be used to measure the wavelength of the light source.
Consider the light from the source falls on the double slits
The demonstration of the double slit experiment is shown in the figure below.
Consider the distance between the two slits
Consider the screen is placed at a distance
The light from monochromatic light source falls on the double slits resulting in the formation of the interference pattern recorded by the screen.
The wavelength
The waves coming out of the two slits are in phase along the central point of screen and add ups constructively resulting in bright central band formation.
Consider the wavelength
The distance
Here,
Hence, the wavelength of the light source can be used TO-DETERMINE the distance between the two slits.
Conclusion:
Thus, the wavelength of the light source can be used TO-DETERMINE the distance between the two slits in double slit experiment.
