Properties of Light and Electricity

Front

What do you call materials that let nearly all light pass through them?

Back

Transparent materials allow nearly all light to pass through them, such as clear glass.

Front

What is a material through which an electric charge cannot move easily?

Back

An insulator is a material that does not allow electric charge to flow easily, like rubber or plastic.

Front

What do you call materials that do not let any light pass through them?

Back

Opaque materials do not allow any light to pass through, such as wood or metal.

Front

What is a material through which an electric charge can move easily?

Back

A conductor is a material that allows electric charge to flow easily, like copper or aluminum.

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 when it passes from one medium to another, like when light enters water.

Front

What do you call the bouncing back of light when it hits a surface?

Back

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

Front

What is the term for materials that allow some light to pass through but not clearly?

Back

Translucent materials allow some light to pass through but scatter it, like frosted glass.

Front

What is the role of a resistor in an electric circuit?

Back

A resistor is a component that resists the flow of electric current, helping to control the current in a circuit.

Front

What is the difference between conductors and insulators?

Back

Conductors allow electric current to flow easily, while insulators do not.

Front

What happens to light when it passes through a prism?

Back

When light passes through a prism, it is refracted and separated into its different colors, creating a spectrum.
