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.
