Q1. Light of wavelength 443 nm in air enters a fishbowl filled with water, then exits through the crown glass wall of the container. Find out the wavelengths of the light (a) in the water and (b) in the glass.

Q2. A 16 cm x 16 cm square loop of wire lies in xy-plane with its bottom edge on the x-axis. The resistance of the loop is 0.490 ohms. A magnetic field parallel to z-axis is given by B= 0.830 y^2 t, where B is in tesla, y in meters, and t in seconds. What is the size of the induced current in the loop at t = 0.470s?
