Refraction is a change in the direction of light rays when they travel from one medium to another. It is the bending of light when it goes through different media.

Angle of Refraction

Light is considered by many scientists to have dual nature, both particle nature and wave nature. First, Particle nature is one in which we consider a stream of packets of energy called photons. Second, Wave nature is considering light as electromagnetic…

d. Diameter of the Sun A Standing on the beach at sunset, you extend the tip of your finger at your full arm length from your face, covering the Sun. Upon moving your finger around, you find that only about half of its width is needed to completely cover the Sun's diameter. You measure your finger width to be 0.5 inches. You know your arm length to be 28.0 inches. You have be told that the Sun is approximately 93 million miles away. Use this information to determine the approximate diameter of the Sun, filling in the table below with the proper quantities measure in meters. 1= ½ finger g= cye level height d = object A = angle from eye level to top of eye level object f= object height from x = Arm length h = Diameter width distance of the Sun What is the diameter of the Sun in Miles? The actual diameter of the Sun more like 865,000 miles. What is the %-Error in your calculated value?
