Light Waves

Front

What is Refraction?

Back

Refraction is the bending of energy waves, such as light, as they pass from one medium to another, changing their direction and speed.

Front

What does Transparent mean?

Back

Transparent refers to a material that allows light to pass through so that objects behind can be distinctly seen.

Front

What is the Electromagnetic Spectrum?

Back

The Electromagnetic Spectrum is the range of all possible energy levels of electromagnetic radiation, including radio waves, visible light, and infrared radiation.

Front

What is Reflection?

Back

Reflection is the bouncing of energy waves, such as light, off the surface of an object.

Front

What is Brightness in terms of light?

Back

Brightness is the intensity of light as perceived by an observer.

Front

What is the difference between Reflection and Refraction?

Back

Reflection involves bouncing off a surface, while refraction involves bending as light passes through different media.

Front

What is a Medium in the context of light waves?

Back

A medium is a substance through which light waves travel, such as air, water, or glass.

Front

What is the role of a Prism in light?

Back

A prism is a transparent object that refracts light, separating it into its component colors.

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 the difference between Transmit and Reflect?

Back

To transmit means to allow light to pass through, while to reflect means to bounce light off a surface.
