I need help with the question in the attached picture, please be detailed and neat with final solutions for parts a, b, and c The energy of a light beam is proportional to the square of its amplitude. Consider a light beam incidenton a material at normal.(a) Determine the percentage of light energy reflected in air from a single surface separating a materialof index 1.40 for light of 1 = 500 nm.(b) When deposited on glass of index 1.60, how thick should a film of this material be in order to reducethe reflected energy by destructive interference?(c) What is then the effective percent reflection from the film layer?

Can you help me with this, I copied the given problem stuff below, and posted screenshots of all 3 parts as 2 screenshots, can you make the answers clear. A relief airplane is delivering a food package to a group of people stranded on a very small island. The island is too small for the plane to land on, and the only way to deliver the package is by dropping it. The airplane flies horizontally with constant speed of 483 km/hour at an altitude of 975 m . The positive x and y directions are defined in the figure. For all parts, assume that the "island" refers to the point at a distance D from the point at which the package is released, as shown in the figure. Ignore the height of this point above sea level. Assume that the acceleration due to gravity is g = 9.80 m/s^2
