The angle of incidence of a ray of light strikes an equilateral triangle prism ABC...
The angle of incidence of a ray of light strikes an equilateral triangle prism ABC of refracting angle 60° is 40°. Calculate:
- the angle of refraction at the first phase
- the angle of emergence
- if the light is incident normally on the first phase AB describe with the aid of a diagram, what is the fate of this light as it passes through the prism?
