A 30-60-90 prism has an index of refraction of n= 1.6. Light is normally incident on the left side of the prism as shown in figure (light coming in on side of 30 and 90 deg angle with the 30 and 60 making the hypotenuse) does the light exit the back of the prism? If, so what is the angle of refraction with respect to the normal to the back surface? If not, what happens to the light?
A bank robber travelling at 75mi/hr in an escape car suddenly sees a barricade 150 m ahead. The robber slams on the breaks following a 0.75 delay (the drivers reaction time) After the brakes are applied, the car decelerates at 4.2m/s^2. Will th..
