_________ are produced by a charge that changes its direction or speed

Electromagnetic waves

______ are charged particles that can produce electric and magnetic fields

Electrons

Electric and magnetic fields oscillate perpendicular to each other and to the direction of the propagating waves, so electromagnetic waves are considered as ________

Transverse waves

Electromagnetic waves can travel in a _____ where there is no matter

Vacuum

Waves that can travel with or without a medium

Electromagnetic waves

Electromagnetic waves travel in a free space at the speed of ______

3x10⁸ m/s

Proponents of the electromagnetic waves theory

James clerk maxwell, Heinrich hertz, Michael faraday, Andre marie ampere, Hans christian oersted

Electromagnetic wave is also denoted as c, the speed of ??

Light

An english scientist who developed a scientific theory to better explain electromagnetic waves

James clerk maxwell

He noticed that electric fields and magnetic fields can couple together to form electromagnetic waves

James clerk maxwell

A german physicist who applied maxwell's theories to the production and reception of radio waves

Heinrich hertz

Unit of frequency of a radio wave

Hertz

Hertz unit

He proved the existence of radio waves in the late 1880s

Heinrich hertz

He used two rods that served as a reciever and a spark gap as the recieving antennae. Where the waves were picked up, a corresponding spark would jump

Heinrich hertz

He is best known for his discovery of electromagnetic induction

Michael faraday

He has contributions to the electromagnetic theory of light, electrical engineering and electrochemistry, and electromagnetic interaction

Michael faraday

He made the revolutionary discovery that a wire carrying electric current can attract or repel another wire next to it that's also carrying electric current

Andre marie ampere

He went on to formulate Ampere's law of electromagnetism

Andre marie ampere

A danish physicist and chemist who discovered that the electric current in a wire can deflect a magnetized compass needle

Hans christian oersted

He discovered electromagnetism using compass

Hans christian oersted

Waves that requires a mediun to propagate is called ?

Mechanical waves

The electromagnetic waves (EM) are often arranged in the order of wavelength and frequency in what is known as the ?

Electromagnetic spectrum

EM spectrum (longest to shortest wavelength / lowest to highest frequency)

Radio wave, Microwave, Infrared, Visible light, Ultraviolet, X-ray, Gamma ray

_____ are bundles of wave energy

Photons

The different types of electromagnetic waves are defined by the amount of energy carried by their _______

Photons

Ionizing radiation

Ultraviolet, X-ray, Gamma ray

Non-ionizing radiation

Radio wave, Microwave, Infrared, Visible light
