How to solve a snells law question

Step-by-step explanation:
Atlantis, a likely mythical island nation mentioned in Plato’s dialogues “Timaeus” and “Critias,” has been an object of fascination among western philosophers and historians for nearly 2,400 years. Plato (c.424–328 B.C.) describes it as a powerful and advanced kingdom that sank, in a night and a day, into the ocean around 9,600 B.C. The ancient Greeks were divided as to whether Plato’s story was to be taken as history or mere metaphor. Since the 19th century there has been renewed interest in linking Plato’s Atlantis to historical locations, most commonly the Greek island of Santorini, which was destroyed by a volcanic eruption around 1,600 B.C.
Refraction is the bending of the path of a light wave as it passes across the boundary separating two media. Refraction is caused by the change in speed experienced by a wave when it changes medium. Lesson 1, focused on the topics of "What causes refraction?" and "Which direction does light refract?" In that lesson, we learned that light can either refract towards the normal (when slowing down while crossing the boundary) or away from the normal (when speeding up while crossing the boundary). The focus of Lesson 2 is upon the question of "By how much does light refract when it crosses a boundary?" In the first part of Lesson 2, we learned that a comparison of the angle of refraction to the angle of incidence provides a good measure of the refractive ability of any given boundary. The more that light refracts, the bigger the difference between these two angles. In this part of Lesson 2, we will learn about a mathematical equation relating these two angles and the indices of refraction of the two materials on each side of the boundary.
