Light Vocabulary

Front

What is a form of energy you can see?

Back

Light Energy

Answer explanation

Light energy is the only form of energy that is visible to the human eye, allowing us to see colors and objects. In contrast, electrical, sound, and mechanical energy cannot be seen directly.

Front

____________ is an energy transfer that happens by vibrations between electric fields and magnetic fields.

Back

Electromagnetic Waves

Answer explanation

Electromagnetic Waves are energy transfers that occur through the vibrations of electric and magnetic fields. This distinguishes them from other options like circuits, reflection, and refraction, which do not involve this specific energy transfer.

Front

Radiation is

Back

the transfer of thermal energy through electromagnetic waves.

Answer explanation

Radiation is defined as the transfer of thermal energy through electromagnetic waves, making the first choice correct. The other options incorrectly describe different phenomena.

Front

____________ happens when light energy bounces off the surface of something.

Back

Reflection

Answer explanation

Reflection occurs when light energy bounces off a surface, allowing us to see objects. This is different from refraction, which involves bending light, and radiation, which refers to energy emission.

Front

The bending or redirection of light energy as it passes between different substances or types of matter is called ______________.

Back

refraction.

Answer explanation

The bending of light as it passes from one medium to another is known as refraction. This phenomenon occurs due to changes in light speed in different substances, unlike reflection, radiation, or absorption.

Front

_____________ is when something is soaked up into another thing or becomes a part of something else.

Back

Absorbtion

Answer explanation

Absorption is the process where something is soaked up into another substance or becomes part of it. This definition aligns perfectly with the term 'absorption', making it the correct choice over the other options.

Front

A prism is something that

Back

is triangular and transparent making it capable of bending light at an angle to separate white light into its colors.

Answer explanation

The correct choice describes a prism accurately as a triangular and transparent object that bends light, allowing it to separate white light into its constituent colors, which is a fundamental property of prisms.

Front

Which of the following is a type of electromagnetic wave that is visible to the human eye?

• Ultraviolet Light
• Infrared Light
• Visible Light
• Microwaves

Back

Visible Light

Answer explanation

Visible Light is the only type of electromagnetic wave among the options that can be seen by the human eye. Ultraviolet Light, Infrared Light, and Microwaves are not visible to us.

Front

What is the term for the phenomenon where light changes direction as it passes through a medium with a different density?

Back

Refraction

Answer explanation

The term for the phenomenon where light changes direction as it passes through a medium with a different density is refraction. This occurs due to the change in speed of light in different materials.

Front

This image shows light being

Back

refracted.

Answer explanation

The image shows light being refracted, which occurs when light passes through different mediums and bends. This is distinct from reflection, absorption, or traveling in a straight line.
