light Behaviors

Discover how light bounces, bends, soaks up, and passes through objects!

Reading Passage Read the passage, then answer the questions that follow.Light is a form of energy that moves in a straight line until it strikes an object or travels from one medium to another. We get light naturally from the Sun. When light hits a shiny object it can be reflected,or bounced back, like in a reflection from a mirror. Some tinted objects, like car windows or sunglasses, can also reflect light.Sometimes light passes through an object and is refracted,or bent.This can make a rainbow or make objects appear different than they really are. Refraction can also happen when light passes through different media like air and water. When light is refracted in water, it can make objects look bent, broken, or larger than they really are. Lenses, like the glass in eyeglasses, also refract light.Light can also be absorbed, or soaked up, by materials. Dark-colored materials absorb more light energy which causes them to heat up faster than lighter colored materials. This also affects how we see color. We cannot see the colors of light which are absorbed. We can only see those which are reflected. Black colored materials absorb all frequencies of light and become very hot. White materials reflect all of the light and stay much cooler. Other colors are visible due to a combination of reflection and absorption.Finally, light can be transmitted, or pass through, some objects. The amount of light that is transmitted depends on the type of material. Objects that are transparent allow all or most of the light to pass through them. Very little light is absorbed orreflected. You can see a clear image of what is on the other side of these objects, like through a clean window. If a material only allows some light to get through, so that objects on the other side appear blurry or unclear, we say that substance is translucent. Frosted glass is an example of a translucent material. Lastly, some materials are opaque. This means that they do not allow any light to pass through. All of the light is either reflected or absorbed. Imagine a window that has been painted black. Match the description with the correct word Reflect bounce back mirror metal object's color shiny objects Refract bend eye glasses change of medium rainbow magnification Students were making observations of how light interacts with objects that have different properties. Which of the following most likely reflected the most light? mirror hand lens black shirt The planet Venus has no light of its own, yet it is visible to us on Earth. This is because Venus _. refracts the Sun's light reflects the Sun's light absorbs the Sun's light transmits the Sun's light Students place a straw in a glass of water as shown. The straw in the water looks broken because of _. refraction reflection absorbtion transmission Karen set up an experiment to see which colored block would increase in temperature most rapidly when placed outdoors in direct sunlight. Her results showed that block 2 gained heat most rapidly and block 4 gained the least heat. This is because block 2 is probably what color? white yellow black green Which picture does NOT illustrate that light travels in a straight lines? A D B C Look at the image. In which picture would the person actually be able to see the light from the candle? top image bottom image both images neither image Choose the word that best completes the sentence. An object that is transparentallows all or most of the light to be transmitted. Little or none of the light will be absorbed or reflected.An object that allows none of the light to be transmitted is said to be opaque. In this case, all light is either reflected or absorbed.A(n) translucentobject allows some of the light to be transmitted. The rest may be either reflected or absorbed.
