5.5.-5.6 Benchmark Review

Front

What is a circuit?

Back

A circuit is a closed path through which electric current flows.

Front

What are insulators?

Back

Insulators are materials that do not allow electricity to flow through them easily. Examples include paper, wood, and glass.

Front

What is SONAR?

Back

SONAR stands for Sound Navigation and Ranging. It uses sound waves to detect objects underwater.

Front

What color in the rainbow has the weakest energy?

Back

RED is the weakest color since it has a long wavelength.

Front

What is an electromagnet?

Back

An electromagnet is a type of magnet that is created by electric current. The more coils of wire wrapped around it, the stronger the magnet becomes.

Front

What is the purpose of using SONAR in ships?

Back

The purpose of SONAR is to send sound waves that bounce back to the ship, creating an image of objects underwater.

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 component colors, creating a rainbow effect.

Front

What is the relationship between wavelength and energy in light?

Back

Longer wavelengths, like red light, have lower energy, while shorter wavelengths, like violet light, have higher energy.

Front

What materials are good conductors of electricity?

Back

Good conductors of electricity include metals like copper, aluminum, and gold.

Front

How does wrapping more coils around an electromagnet affect its strength?

Back

Wrapping more coils around an electromagnet increases its strength.
