The rays have to travel a larger part of the atmosphere because they are very close to the horizon. So light other than red is scattered away.
IV:The detergents
DV: the dishes
Hypothesis: The expensive dish detergent cleans better then cheaper detergent
Control: the amount of detergent used
Contants: the detergents
Answer: Light Refraction
Explanation:
Light rays travel in straight lines. When they strike an opaque surface, the rays bounce, and light is reflected back to your eye so that you see an image. When light strikes a transparent object, some of the light passes through. If that light strikes the object straight on, it continues to travel in a straight line. If the light enters the transparent object at an angle, though, it changes direction, bending.This bending of light is called refraction. Refraction occurs because light entering an object slows down. When it enters at an angle, one side of the light ray enters before the other, slowing down first.Looking from above, an object under water appears larger than it does in air. It's not that the image the light gave our eyes is bigger. It's that the image is actually closer to our eyes, since the light is not passing straight down, but is instead bending relative to the water's surface. Light passing straight down would be perpendicular to the water's surface, like the vertical line on the letter T.
It is the proximal convoluted tubule. It is a portion of the kidney which leads to the loop of Henle, from the Bowman's capsule. The densely present microvilli increase the surface of the luminal area, thereby improving their absorptive potential.
