Amplify Light Waves Key Concepts

Front

What is light?

Back

Light is a form of energy that travels in waves and can be seen by the human eye.

Front

What does it mean for light to carry energy?

Back

When light carries energy, it can cause changes in materials, such as heating them or causing chemical reactions.

Front

What are wavelengths in relation to light?

Back

Wavelengths are the distances between successive peaks of a light wave, and different types of light have different wavelengths.

Front

What happens to light when it is reflected?

Back

When light is reflected, it bounces off a surface without being absorbed, meaning the material does not change.

Front

What occurs when a material absorbs light energy?

Back

When a material absorbs light energy, it undergoes a change, which can include heating or altering its state.

Front

How does light travel?

Back

Light travels in straight lines unless it interacts with materials that can bend or reflect it.

Front

What is the difference between reflection and absorption of light?

Back

Reflection is when light bounces off a surface, while absorption is when light energy is taken in by a material, causing a change.

Front

What is visible light?

Back

Visible light is the portion of the electromagnetic spectrum that can be seen by the human eye, typically ranging from wavelengths of about 400 to 700 nanometers.

Front

What are the different types of light?

Back

Different types of light include visible light, ultraviolet light, infrared light, and others, each with varying wavelengths and properties.

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, including radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.
