The fluids and obvious tissues of the attention that refract mild rays passing via them in the direction of the retina: the cornea, aqueous humor, lens, and vitreous humor.
When a mild ray enters a refracting medium, it's far determined that the significance of the attitude of refraction is identical to 1/2 the perspective of reflection.
Dielectric, interface, and glass are substances that transmit and replicate mild specularly, and also manage refraction. The primary two are used for limitations of volumes which might be meant to symbolize strong gadgets of the refracting medium.

Answer:
Explanation: The claim the Christopher Columbus discovered America is not true. Below are some claims that proves this discovery as untrue.
1. Christopher Columbus made four separate trips that started with the one in 1492. Columbus landed on various Caribbean islands that are now the Bahamas as well as the island later called Hispaniola. He also explored the Central and South American coasts. But he didn’t reach North America which of course was already inhabited by Native Americans and he never thought he had found a new continent.
2. Christopher Columbus introduced the Americas to Western Europe during his four voyages to the region between 1492 and 1502. He paved the way for the massive influx of western Europeans that ultimately form several new nations including the United States, Canada and Mexico. But he never discovered America because there were plenty of people already there when he arrived.
