The discoverer of X-rays on November 8, 1895.

Roentgen took an X-ray of a wooden box showing hidden weights.

An X-ray image revealed a hidden flaw in a hunting rifle.

Roentgen photographed his wife's hand showing her bones and rings.

Roentgen named X-rays after the unknown X in math.

A type of electromagnetic radiation that we feel as heat.

A device that detects infrared radiation emitted by people or animals for security.

The range of wavelengths that are visible to the human eye, from violet (0.4 mm) to red (0.7 mm).

The phenomenon where white light is dispersed into various colors when it passes through a prism.

White light is made up of a mixture of different colors of light.

Weightless packets of pure energy (photons) with no charge, travelling at 3 x 10^8 m/sec.

The greater the frequency of the wavelength, the greater the energy of the photon.

X-rays travel in straight lines; deflected but linear in trajectory.

X-rays are absorbed differently by materials based on atomic structure and wavelength.

X-rays can remove electrons from atoms, forming ions used for measuring exposure.

Waves that consist of oscillating electric and magnetic fields perpendicular to each other and the wave's direction.

The range of all types of electromagnetic radiation, varying by wavelength.

Electromagnetic waves with long wavelengths, emitted by transmitters, stars, and lightning.

High-frequency radio waves with wavelengths measured in centimeters, used to cook food and transmit information.

An appliance that uses microwaves to heat food by causing water and fat molecules to vibrate.

A system that uses radio waves to detect the position and speed of objects, often used in weather forecasting.

Microwaves can transmit information effectively since they penetrate environmental conditions like rain and snow.

Large doses of radio waves are suspected to cause health issues such as cancer and leukemia.

Uses microwaves, requires line of sight to transmit.

Clouding of the lens in eyes from microwave exposure.

Waves just below visible light, felt as heat.

Uses infrared to enhance visibility in darkness.

Type of IR experienced as heat daily.

Devices that operate using infrared waves.

A device that produces coherent light, different from a light bulb.

A type of light emitted by the sun and special lamps, often called 'UV'.

A layer protecting Earth from UV radiation, filtering out 95% of heat.

The highest energy electromagnetic waves, can kill cancer cells.

A drink that absorbs X-rays to show intestines clearly in imaging.

A discrete bundle of energy in electromagnetic radiation, traveling at the speed of light.

A unit of measurement for the energy of photons in electromagnetic radiation.
