Physical Science Chapter 7 – Flashcards

Which of the following is luminous?

A source of light given off as a result of high temperatures is said to be

An idealized material that absorbs and perfectly emits electromagnetic radiation is a

Electromagnetic radiation is given off from matter at any temperature. This radiation is called

Light interacts with matter by which process?

Materials that do not allow the transmission of any light are called

Light is said to travel in straight-line paths, as light rays, until it interacts with matter. A line representing the original ray before it interacts with matter is called a (an)

The image you see in the mirror is

Refraction of light happens when light undergoes

The ratio of the speed of light in a vacuum to the speed of light in some transparent materials is called

The part of the electromagnetic spectrum that our eyes can detect is

The component colors of sunlight were first studied by

The color order of longer-wavelength to smaller-wavelength waves in the visible region is

The separation of white light into its component colors is

Polarization of light is best explained by considering light to be

Light in one plane is transmitted and light in all other planes is absorbed. This is

The photoelectric effect is best explained by considering light to be

The concept that vibrating molecules emit light in discrete amounts of energy, called quanta, was proposed by

The photoelectric effect was explained, using Planck's work, by

Today, light is considered to be packets of energy with a frequency related to its energy. These packets are called

Fiber optics transmits information using

A luminous object

An object is hot enough to emit a dull red glow. When this object is heated even more, it will emit

The difference in the light emitted from a candle, an incandescent lightbulb, and the sun is basically from differences in

You are able to see in shaded areas, such as under a tree, because light has undergone

An image that is not produced by light rays coming from the image, but is the result of your brain's interpretations of light rays is called a(an)

Any part of the electromagnetic spectrum, including the colors of visible light, can be measured in units of

A prism separates the colors of sunlight into a spectrum because

Which of the following can only be explained by a wave model of light?

The polarization behavior of light is best explained by considering light to be

Max Planck made the revolutionary discovery that the energy of vibrating molecules involved in blackbody radiation existed only in

Today, light is considered to be

As a temperature of an incandescent object is increase,

Is it possible to see light interacting with matter?

The electromagnetic wave model defines an electromagnetic wave as having

Of the following, the electromagnetic wave with the shortest wavelength is

Of the following, the electromagnetic wave with the lowest energy is

Green grass reflects

Green grass absorbs

We see a blue sky because

A pencil is placed in a glass of water. The pencil appears to be bent. This is an example of

A one-way mirror works because it

A mirage is the result of light being

A glass prism separates sunlight into a spectrum of colors because

Polaroid sunglasses work best in eliminating glare because

The condition of farsightedness, or hyperopia, can be corrected with a (an)

Today, light is considered to be a stream of photons with a frequency related to its energy. This relationship finds that

An instrument that produces a coherent beam of single-frequency, in-phase light is a

The special theory of relativity is

The general theory of relativity explains

Comparing measurements made on the ground to measurements made in a very fast airplane would find that
