Light Flashcard 1 - EM Spectrum/Reflection

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, which includes visible light, radio waves, X-rays, and more.

Front

What is reflection in terms of light?

Back

Reflection is the bouncing back of light when it hits a surface.

Front

What type of surface causes light to reflect in many different directions?

Back

A rough surface.

Front

What is regular reflection?

Back

Regular reflection occurs when light reflects off a smooth surface at a consistent angle.

Front

How does light travel?

Back

Light travels in a straight line.

Front

What is a light source?

Back

A light source is any object that emits light, such as the sun, a lamp, or a candle.

Front

What happens to light when it hits a smooth surface?

Back

It reflects at a consistent angle, resulting in a clear image.

Front

What is the difference between rough and smooth surfaces in terms of light reflection?

Back

Rough surfaces scatter light in many directions, while smooth surfaces reflect light uniformly.

Front

What is an example of a smooth surface?

Back

A mirror is an example of a smooth surface that reflects light regularly.

Front

What is the term for the angle at which light hits a surface?

Back

The angle of incidence.
