Light Waves and Their Properties

What is the color black?

• A color that reflects all wavelengths of light

• The absence of visible light, it absorbs all wavelengths of light and turns them to heat

• A shade of gray that is very dark

• A color that is often associated with sadness

What are the colors of visible light in order?

• Red, Orange, Yellow, Green, Blue, Indigo, Violet

• Red, Yellow, Green, Blue, Violet, Orange, Indigo

• Blue, Green, Yellow, Red, Violet, Orange, Indigo

• Orange, Red, Violet, Blue, Green, Yellow, Indigo

What is absorption?

• The process by which light waves are taken in by a material.

• The process of reflecting light waves off a surface.

• The process of scattering light waves in different directions.

• The process of emitting light waves from a source.

What are transparent materials?

• Materials that allow light to pass through clearly.

• Materials that reflect light completely.

• Materials that absorb all light.

• Materials that scatter light in all directions.

A ray of light is what type of wave?

• Longitudinal and mechanical

• Electromagnetic and transverse

• Acoustic and longitudinal

• Gravitational and transverse

Every color has a different wavelength - this means they have

• different amounts of energy

• the same frequency

• no effect on temperature

• identical wavelengths

What is the electromagnetic spectrum?

• the range of all types of radiation, including visible light, radio waves, and X-rays.

• a type of wave that only includes visible light.

• the distance between two peaks of a wave.

• a measure of the speed of light in a vacuum.

What is reflection?

• the bending of light waves as they pass through different mediums.

• the bouncing back of light waves when they hit a surface.

• the absorption of light waves by a surface.

• the scattering of light waves in different directions.

What is light energy?

• The energy carried by light waves, which can be transformed into other forms of energy, such as heat.

• A type of energy that is only visible to the human eye.

• Energy that is produced by chemical reactions in the dark.

• The energy stored in the nucleus of an atom.

What is the color white?

• The absence of all visible light.

• The presence of all visible light, it reflects all wavelengths of light.

• A color that absorbs all wavelengths of light.

• A shade of gray that reflects some light.
