Front

What happens to gas particles when thermal energy is added?

Back

Particles move rapidly and randomly in all directions.

Front

What property of electromagnetic waves allows infrared radiation to be used in medical imaging?

Back

The waves can be absorbed differently by different tissues.

Front

What does Newton's First Law of Motion state?

Back

An object at rest stays at rest and an object in motion stays in motion unless acted upon by an external force.

Front

How does wavelength relate to energy in the electromagnetic spectrum?

Back

As wavelength decreases, energy increases.

Front

What is the main difference between electromagnetic waves and mechanical waves?

Back

Electromagnetic waves can travel through a vacuum, mechanical waves cannot.

Front

What is thermal energy?

Back

The energy that comes from the temperature of matter; it is the total kinetic energy of particles in an object.

Front

What is infrared radiation?

Back

A type of electromagnetic radiation with wavelengths longer than visible light, often used in thermal imaging.

Front

What is Newton's First Law of Motion also known as?

Back

The law of inertia.

Front

What is the electromagnetic spectrum?

Back

The range of all types of electromagnetic radiation, including visible light, radio waves, and X-rays.

Front

What is a mechanical wave?

Back

A wave that requires a medium (solid, liquid, or gas) to travel through.
