Behavior of Light

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).

Front

What is reflection of light?

Back

Reflection of light is the bouncing back of light rays when they hit a surface.

Front

What is refraction of light?

Back

Refraction of light is the bending of light as it passes from one medium to another medium with a different refractive index.

Front

What is absorption of light?

Back

Absorption of light is the process by which light is taken in by a material and converted to other forms of energy.

Front

What is a translucent material?

Back

A translucent material allows some light to pass through but scatters it, making objects behind it appear blurry.

Front

What is a transparent material?

Back

A transparent material allows light to pass through without significant scattering, making objects behind it clearly visible.

Front

What is an opaque material?

Back

An opaque material does not allow any light to pass through, making it impossible to see through.

Front

What is the law of reflection?

Back

The law of reflection states that the angle of incidence is equal to the angle of reflection.

Front

What is the difference between reflection and refraction?

Back

Reflection is the bouncing back of light, while refraction is the bending of light as it passes into a different medium.

Front

What is the role of a prism in light behavior?

Back

A prism refracts light, separating it into its component colors (spectrum) due to different wavelengths bending at different angles.
