One dark night, as part of your SEAL tralning, you are scuba diving when your foot gets caught in some machinery underwater. You have a waterproof laser, but the battery Is almost dead, so you'll have to carefully plan how to signal for help. Good thing you took this course! You calculate that your squad will see the laser if the angle In the air (n = 1.00) is 80 degrees. What angle should you choose in the water (n 1.33)7 All angles are defined at the water-air boundary in the usual convention. Assume the surface of the water is flat.
