Waves and Light

Front

What is refraction?

Back

Refraction is the bending of light as it passes from one medium to another due to a change in its speed.

Front

What happens to white light when it passes through a prism?

Back

White light is refracted and separated into its component colors (spectrum) due to different wavelengths bending at different angles.

Front

What is the primary color of light?

Back

The primary colors of light are red, green, and blue (RGB). They can be combined to create other colors.

Front

What color does a paper appear if it absorbs all colors except green?

Back

The paper will appear green because it reflects the green wavelengths of light.

Front

What is diffraction?

Back

Diffraction is the bending of light waves around obstacles or through openings, causing spreading and interference patterns.

Front

What is the result of combining all three primary colors of light?

Back

Combining all three primary colors of light (red, green, and blue) produces white light.

Front

What is reflection?

Back

Reflection is the bouncing back of light when it hits a surface that does not absorb the light.

Front

What is the difference between absorption and reflection of light?

Back

Absorption is when light is taken in by a material, while reflection is when light bounces off a surface.

Front

What is the role of lenses in optics?

Back

Lenses refract light to focus or disperse it, allowing for magnification or correction of vision.

Front

What is the speed of light in a vacuum?

Back

The speed of light in a vacuum is approximately 299,792 kilometers per second (km/s).
