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.

Give your knowledge of these things in your paper, you will compare and contrast analog and digital signals to determine which is more reliable for encoding and transmitting information. you’ll compare these features: signal shape numerical values for signal measurements amount of data that can be transmitted energy requirements privacy and security (ability of the signal to be encoded in a secret code) clarity of signal in the space provided, write down what you already know about any of these features. if you’re not sure, write down questions you might have about the features.
