(3 points) Question 1): In the discussion of electromagnetic induction, we learned that if a magnet is brought rapidly closer to a coil (or to a solenoid) an electric current will be induced in that coil. What do we observe if we bring the magnet close to the coil with much higher speed than before? (3 points) Question 2: In the above experiment, what will happen if we flip the polarity of the magnet (e.g., flip N side of the magnet with S side of it) and then bring it rapidly close to the coil? (3 points) Question 3: Which attribute (or parameter) of the light wave is responsible for the color of the light? (4 points) Question 4: We observe that the light bends when it passes from a transparent
