Angle of incidence and refraction

AI Thread Summary
The discussion focuses on the formulas related to the sine of the angle of incidence, the sine of the angle of refraction, and the index of refraction, all of which are connected to Snell's law. To calculate the sine of an angle, one can use a right triangle where the sine is the ratio of the length of the opposite side to the hypotenuse. The index of refraction can be determined by taking the ratio of the sine of the angle of incidence to the sine of the angle of refraction. The conversation emphasizes the importance of understanding these concepts for calculating the refractive index of a medium. Overall, the thread serves as a reminder of the fundamental relationships in optics.

Hello PF users hope all is well!
I need a reminder of the formulas needed in order to get

"Sine of angle of incidence"

"Sine of angle of refraction"

And "Index of refraction".

The only information I have available now is

"Angle of incidence" And "Angle of refraction"

I'm guessing they're all along the lines of Snell's law

i hope you wish to know about calculating the refractive index of a medium through the info about angle of incidence and angle of refraction.
what is snell's law? and how it is applied?
and how to calculate sine of an angle.
its simple to draw a right angle triangle with base angle 'equal to angle of your choice' and take the ratio of perpendicular length with hypoteneuse , then you get the sine of that angle.
or go to the trigonometric table of sine of the angles and get values and calculate index of refraction = ratio of sine of the angle of incidence and refraction.
 
Thank you for the help, I can clearly recall how to calculate it.
 

Thread 'Pentaprism with magnification, which surface is curved?'

I would like to use a pentaprism with some amount of magnification. The pentaprism will be used to reflect a real image at 90 degrees angle but I also want the reflected image to appear larger. The distance between the prism and the real image is about 70cm. The pentaprism has two reflecting sides (surfaces) with mirrored coating and two refracting sides. I understand that one of the four sides needs to be curved (spherical curvature) to achieve the magnification effect. But which of the...
