A submarine is 3.00 x 10^2 m horizontally from shore and 120.0 m beneath the surface of the water. A laser beam is sent from the submarine so that the beam strikes 2.10 x 10^2 m from the buildingstanding on the shoreand the laser beam hits the target on the top of the building. Use n=1.333 for the refractive index of water. A)Calculate the angle of incidence ?1 on the water/air interface.

B)Calculate the angle of refraction ?2.
C)Find angle ? with the horizontal.
D)Find the height h of the building
