Explanation:
At each reflecting surface (benzene and glass) there will be 180 degree phase change.
Now, for constructive interference the optical path in benzene is .
Formula to calculate thickness of a benzene thin film is as follows.
Optical path length through benzene () =
Hence, substituting the given values into the above formula as follows.
Optical path length through benzene =
d =
=
= (as 1 nm =
= 204.9 m
Thus, we can conclude that minimum thickness of benzene is 204.9 m.
<h3>What is spectrometric method?</h3>
- A technique called spectrophotometry uses light intensity measurements as a beam of light travels through a sample solution to determine how much a chemical compound absorbs light.
- Every chemical either absorbs or transmits light across a specific spectrum of wavelengths, according to the fundamental principle.
- There are two main techniques used among the various forms of spectrophotometry:
- ultraviolet-visible range spectrophotometry, which examines the reflectance of certain spectra,
- and absorption spectrophotometry, which examines the absorption of radiation and particular spectra of light.
- Applications of spectrophotometry are useful for determining how well gases, liquids, and solids transmit, reflect, and absorb light.
