Question

Morty is depressed. One night while sitting on the pier, aimlessly shining his laser into the water, he sees a glint from a shiny object. Specifically, he sees this light when he shines the laser 2.4 m in front of him while holding the pointer 1.8 m above the water. If the water is 5.5 m deep, what is the horizontal distance to the shiny object on the ocean floor? (Note: the index of refraction for water is 1.33)
