Answer:

Answer:

D or 49.7°

Explanation:

You are given the equation and all the information you need, so you simply need to understand what the question asks for and answer appropriately. Notice that the light wave travels from the water to air. This means that water should be labelled with a "1" as it comes prior to air, which should be labeled "2". Thus, all you need to do, is plug and chug:

\theta_2 = sin^(-1)((n_1sin(\theta_1))/(n_2)) = sin^(-1)(((1.33)sin(35))/(1))

\theta_2 = sin^(-1)(0.763) = 49.7^o

And, therefore, your answer is D, 49.7°.

France Capitulates to Nazi Germany. On June 22, 1940, the French state approved a cease-fire with Nazi Germany just six weeks after the Nazis began their incursion of Western Europe.

Paris began preparing for combat in September 1939, when Nazi Germany overran Poland, but the combat appeared far beyond until May 10, 1940, when the Germans invaded France and immediately took the French troops. The French administration left Paris on June 10, and the Germans controlled the capital on June 14.

25 % of the population was in controlled by Germany after France fell to the Axis power. Germany ruled over France and made things that caused the French people to create a revolution. This was one of the greatest revolution so far in the history where the French people united just to get their freedom back.
