Electromagnetic Radiation and the EMS Spectrum

Flashcards covering the definitions, examples, safety, and components of electromagnetic radiation based on the lecture notes.

Electromagnetic radiation

Energy that travels thru space as waves made of electric magnetic field

Electromagnetic Spectrum Examples

Radio waves, microwaves, and X-rays

Hertz ($Hz$)

The unit used to measure the frequency of electromagnetic waves.

Visible light spectrum

The part of the electromagnetic spectrum that human eyes can detect.

Wavelength

The distance between one wave crest and the next.

Microwaves

Waves that cook food by vibrating water molecules.

Ultraviolet light risks

Excessive exposure can cause sunburns, skin cancer, and eye damage.

EMS waves (Least to Most Dangerous)

Radio, Microwave, Infrared, visible, ultraviolet, X-ray, Gamma ray.

Electromagnetic wave composition

An electric field and magnetic field.

Radio wave uses

Radio/TV broadcasting, mobile phone signals, and gps.

Non ionizing waves

Waves considered safe, including radio, microwaves, infrared, and visible light.
