What value did you calculate for the index of refraction of the acrylic block in part 2? how does your value compare to the accepted value of 1.50? calculate the percentage error. different materials have distinct indexes of refraction. explain how you might identify a material based on experiments like this one. mention at least one of the difficulties in identifying materials based on their indexes of refraction.

Is it possible to use the energy from two atoms colliding to create a clean burning lasting fuel source with a large amount of force? is it also possible to harness that energy from the two atoms colliding to create a clean energy source that will last for years from just two atoms colliding. is there a possibility to control and store that energy for years but slowly let the energy out enough to power cities cheaper and faster.
