SUMMARY

The discussion centers on determining the angle of polarization and the corresponding angle of refraction for ethyl alcohol. Participants clarify that the question pertains to linearly polarized light and the effects of ethyl alcohol on light polarization. The refractive index of ethanol is essential for calculations, and resources such as the provided link may assist in understanding the underlying physics concepts.

PREREQUISITES
  • Understanding of linear polarization of light
  • Knowledge of refractive index, specifically for ethyl alcohol
  • Familiarity with birefringence and its measurement
  • Basic principles of optics and light behavior
NEXT STEPS
  • Research the refractive index of ethyl alcohol and its implications on light polarization
  • Study the formula for calculating the angle of polarization in optics
  • Explore birefringence measurement techniques in liquid mediums
  • Investigate the effects of electric fields on the polarization of light in materials
USEFUL FOR

Physics students, optical engineers, and researchers interested in the properties of light and its interaction with materials like ethyl alcohol.

How do you find the angle of polarization? What is the formula? Its not in my physics book and I looked online and couldn't find it.
 
Physics news on Phys.org
Polarization of what? Of some linearly polarized light? Or of a polarizing filter? What is the context of the question?
 
the angle of polarization of ethyl alcohol.

Sorry, I'm still not understanding the question. Are you asking how ethyl alcohol can affect the polarization of light? Are you going to apply an electric field across the ethyl alcohol and measure the birefringence?
 
ok the question reads exactly like this
Find the angle of polarization and the corresponding angle of refraction for ethyl alcohol.
That is all it says.
 
Perhaps you are referring to http://scholar.hw.ac.uk/site/physics/topic8.asp?outline=" ?
You'll need the refractive index of ethanol
