Answer to Question 1

Light is scattered when visible light is deflected from its path and sent out in all directions. Light is scattered in the atmosphere by very small objects, such as air molecules, fine dust particles, water molecules, and some pollutants. Clouds appear white because cloud droplets scatter all wavelengths of visible light.
Light is reflected when visible light bounces off a surface at the same angle at which it strikes the surface. An example of reflection is the appearance of sun pillars, which are caused by the reflection of sunlight off ice crystals.
The refraction of light is the bending of light as it is transmitted at an angle through substances of different densities. Examples of refraction include mirages, halos, sundogs, tangent arcs, and rainbows.
The passage of white light through a prism is an example of selective refraction, also called dispersion.

Answer to Question 2

B

People who have myopia, or nearsightedness, are not able to see objects at a distance but only up close. It occurs when the cornea is either curved too steeply, the eye is too long, or both. This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition. Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.

Many people have small pouches in their colons that bulge outward through weak spots. Each pouch is called a diverticulum. About 10% of Americans older than age 40 years have diverticulosis, which, when the pouches become infected or inflamed, is called diverticulitis. The main cause of diverticular disease is a low-fiber diet.

A cataract is a clouding of the eyes' natural lens. As we age, some clouding of the lens may occur. The first sign of a cataract is usually blurry vision. Although glasses and other visual aids may at first help a person with cataracts, surgery may become inevitable. Cataract surgery is very successful in restoring vision, and it is the most frequently performed surgery in the United States.
