A block of clear acrylic sits on top of a block of glass. A ray of light traveling in the glass is incident on the acrylic/glass interface at an angle of [t1] degrees with respect to the normal. The light has wavelength [wa] nm in the acrylic and [wg] nm in the glass.  What is the refracted angle into the acrylic as measured from the normal to the interface? Give your answer in degrees and round to one decimal place. Show all work starting from Snell’s law to receive full credit.

The image below contains an inductor of inductance L (Henries) and a time-varying current from a power supply flowing from A to B. (a) At what rate would the current through the inductor have to change to induce a negative emf of V (volts) in the inductor? Use the variables given in the problem to write your answer. Include the correct sign. (b) what direction would that induced current flow (A to B or B to A) and why?  Write your answers to (a) and (b) in the text box and include a one-sentence explanation of your part (b) answer to receive full credit.
