Concept explainers
Minimum thickness of the layer of air if the glass appears bright and dark.
Answer to Problem 45P
The minimum thickness if glass appears bright is
The minimum thickness if glass appears dark is
Explanation of Solution
Given:
Wavelength,
Formula used:
Dark bands will occur when
The light rays are perpendicular to the plates, the extra path length equals to
Where,
Calculation:
Calculation for the constructive interference, the net phase change is
Hence, the minimum thickness is
Calculation for the destructive interference, the net phase change is
Hence, the minimum non-zero thickness is
Conclusion:
The minimum thickness is
