Light Flashcard 1 - EM Spectrum/Reflection

Front

What is the electromagnetic (EM) spectrum?

Back

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

Front

Put the EM waves in increasing frequency order: radio, visible light, ultraviolet.

Back

The correct order is: radio, visible light, ultraviolet.

Front

What is reflection in terms of light?

Back

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

Front

Which type of surface causes diffuse reflection?

Back

A rough surface causes diffuse reflection, scattering light in many directions.

Front

What type of visible light has the highest energy?

Back

Violet light has the highest energy among visible light.

Front

What is the difference between specular and diffuse reflection?

Back

Specular reflection occurs on smooth surfaces, producing clear images, while diffuse reflection occurs on rough surfaces, scattering light.

Front

What is the role of a mirrored surface in reflection?

Back

A mirrored surface reflects light in a uniform direction, creating a clear image.

Front

What is the order of the EM spectrum from lowest to highest frequency?

Back

The order is: radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, gamma rays.

Front

What happens to light when it hits a rough surface?

Back

Light is reflected in many different directions when it hits a rough surface.

Front

What is the term for the bending of light as it passes from one medium to another?

Back

Refraction is the bending of light as it passes from one medium to another.
