Energy and Electromagnetic Radiation

A collection of flashcards covering definitions and key concepts related to energy and electromagnetic radiation.

Energy

The measurable ability to do work.

Chemical Energy

Energy stored in the bonds of atoms.

Electrical Energy

Energy resulting from the movement of electrons.

Nuclear Energy

Energy that holds the nucleus of an atom together.

Thermal Energy

Heat energy.

Gravitational Potential Energy

Energy stored in an object's height.

Kinetic Energy

Energy from the movement of molecules.

Photons

Particles of energy that travel at the speed of light and can behave as both particles and waves.

Electromagnetic Spectrum

All possible forms of electromagnetic radiation organized by wavelength.

Radio Waves

Low energy electromagnetic radiation used in communication.

Infrared Radiation

Electromagnetic radiation used for thermal sensing.

X-Rays

A form of electromagnetic radiation commonly used in medical imaging.

Ultraviolet Radiation

Electromagnetic radiation that can cause ionization and damage to living tissue.

Remote Sensing

The technology that uses electromagnetic radiation to gather data about the Earth from satellites.

MRI (Magnetic Resonance Imaging)

Medical imaging technique that uses radio waves and magnets to create images of tissues.

Luminol

A chemical that emits visible light when it reacts with iron in blood, used in crime scene investigations.

Hubble Space Telescope

Telescope that uses mirrors to collect and focus visible light for clearer images of the universe.

Ionizing Radiation

Radiation that can detach electrons from atoms, potentially causing tissue damage.

Non-Ionizing Radiation

Radiation that does not carry enough energy to detach electrons from atoms.

Visible Light

Electromagnetic radiation that can be seen by the human eye, ranging from 400nm to 800nm.
