A glass prism has as principle cross section a triangle ABC such that ABC= 60°.
A ray SI of red light hits, in air under an angle of incidence of
60°, the face AB of the prism.
The index of refraction of the prism for the incident red light
is n=1.64
1- Study the path of the say SI till it leaves the prism.
2-Determine the value of the angle of incidence of the ray Si so that it would leave the prism grazing it's face AC. ​

Hey student studies gravity using objects that have the same mass which two objects have the greatest gravitational force acting between them a. 100kg 1.0m 100kg b. 100kg 2.0m 100kg c. 100kg 2.0m 100kg big d. 100kg big 3.0m 100kg big

Why are graphs useful when interpreting data

Abeverage can is made of 3004-h19 aluminum alloy (elastic modulus 69 gpa, tensile yield strength 285 mpa, density 2.72 g/cm^3). the dimensions on the can are approximated as a thin-walled cylinder with a height of 4.83 inches, diameter of 2.60 inches. empty the can has a mass of 14.2 g. determine: a. the wall thickness of the cylinder b. assuming a pinned-pinned condition what is the critical load? c. assuming a fixed-fixed condition what is the critical load?
