Two non-parallel light rays initially converge to a single point on a screen. A rectangular block of glass is now placed somewhere in front of the screen, in the path of the light rays, so that the glass surface is parallel to the screen. Where is the new convergence point of the rays? The choices are:
On the screen(unchanged)
Behind the screen
Inside the glass box
toward glass block in front of the screen...
And why

  1. Use Snell's law to figure this out. Drawing a diagram should help. I will be glad to critique your thought process.
