Unit 07: Light Practice

Front

What is the visible spectrum?

Back

The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye, consisting of light wavelengths from approximately 400 to 700 nanometers.

Front

What type of light is not part of the visible spectrum?

Back

Infrared light is not part of the visible spectrum; it has longer wavelengths than visible light.

Front

What are rays in the context of light?

Back

Rays are straight lines that represent the path of light waves.

Front

What conclusion can be drawn about the path of light?

Back

Light travels in a straight line.

Front

What does it mean for an object to be transparent?

Back

A transparent object allows light to pass through it without significant scattering.

Front

What does it mean for an object to be translucent?

Back

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

Front

What does it mean for an object to be opaque?

Back

An opaque object does not allow any light to pass through it.

Front

What is reflection in terms of light?

Back

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

Front

What is refraction?

Back

Refraction is the bending of light as it passes from one medium to another, changing its speed.

Front

What is absorption in the context of light?

Back

Absorption is the process by which an object takes in light energy and converts it to other forms of energy.
