The wave-particle duality of light describes light as...

• a wave only

• a particle only

• both a wave and a particle

• neither a wave nor a particle

Refraction of light is evidence that _________________.

• the nature of light is unknown

• light is both a particle and a wave

• light is a particle phenomenon

• light is a wave phenomenon

______________ can be seen when white light is separated through a prism.

• visibility

• color

• brightness

• intensity

Which statement accurately describes what a prism does?

• A prism refracts and separates white light into the individual colors of light.

• A prism absorbs certain wavelengths of visible light on one side and transmits them out of the other end.

• A prism reflects white light until the individual colors of light are produced.

• A prism transmits light through its structure and separates white light into the individual colors of light.

How are we able to perceive an object as being the color green?

• All colors of visible light are absorbed by an object and then green light is reflected into our eye.

• All colors of visible light are transmitted to an object, but only green light is absorbed by the object.

• All colors of visible light are transmitted to an object, but only green light is reflected to our eye by the object.

________________ is the change in the direction of a wave that occurs as the wave changes speed when moving from one medium to another.

• Refraction

• Reflection

• Absorption

• Transmission

The color that you see in an object is the color it is _______________.

• Reflecting

• Absorbing

• Scattering

• Dispersing

As the frequency of an electromagnetic wave increases, the amount of energy in that wave...

• decreases

• increases

• stays the same

Identify which property of light best explain the light phenomenon below.

Sky appears blue in a clear cloudless daytime.

• Dispersion

• Scattering

• Interference

• Diffraction

What color of light do photographers usually use in dark rooms? Why?

• Yellow light since paper is not sensitive to this color.

• Regular light may be used since it won't affect the printing.

• Red light does not cause the film to be exposed since it has low energy.

• Violet light has the highest energy which is used to give color to the pictures.
