Question 1 : We take a rectangular glass slab with a thickness of 10 mm. There are perfectly aligned rulers on the two long surfaces, ruler A and ruler B. The glass has an index of refraction of 1,5 with no dispersion. We aim a laser at the zero mark of ruler A at an angle of 45° to a normal line that is perpendicular to ruler A. It refracts through the glass and exits from the other side, through ruler B. At what angle (in degrees) from a normal line perpendicular to ruler B does the laser beam exit? Answer to one digit after the decimal point

Question 2 : We take a rectangular glass slab with a thickness of 15 mm. There are perfectly aligned rulers on the two long surfaces, ruler A and ruler B. The glass has an index of refraction of 1,4 with no dispersion. We aim a laser at the zero mark of ruler A at an angle of 40° to a normal line that is perpendicular to ruler A. It refracts through the glass and exit from the other side, through ruler B. At what distance (in mm) from the zero mark of ruler B does the laser beam exit? Answer to 2 digits after the decimal point

Question 3 : We take a rectangular glass slab with a thickness of 10 mm. There are perfectly aligned rulers on the two long surfaces, ruler A and ruler B. The glass has an index of refraction of 1.3 with no dispersion. We aim a laser at the zero mark of ruler A at an angle such that it exits from the other surface at a distance of 2 mm from the zero mark of ruler B. At what angle of incidence (in degrees) to a normal line that is perpendicular to ruler A did the laser beam enter? Answer to one digit after the decimal point
