EM Waves

Electromagnetic Waves

A type of wave that propagates through space, it consists of electric and magnetic fields oscillating perpendicular to each other and to the direction of propagation.,

Electromagnetic Radiation

Refers to the energy that is emitted or radiated by charged particles in the form of electromagnetic waves.

Electromagnetic Spectrum

Refers to the entire range of electromagnetic radiation, which is categorized based on the wavelength or frequency of the electromagnetic waves.

Speed of Light

Speed in which EM waves travel in a vacuum

Transverse Waves

Type of wave corresponding to EM Waves, it means that the oscillations of the electric and magnetic fields are perpendicular to the direction of wave propagation. 

Electric and Magnetic

Two fields that oscillate in an Electromagnetic Wave

Crest

The highest point of the wave above the equilibrium position, it is the peak of the wave where the energy is concentrated.

Trough

The lowest point of the wave where the particles of the medium are displaced the most in the opposite direction to the crest.

Amplitude

The maximum displacement of a point from its equilibrium (rest) position, measures how far the particles of the medium move from their equilibrium position during the wave’s oscillation.

larger, energy

The ________ the amplitude, the more ______ the wave carries

Wavelength

Distance between two consecutive crests or two consecutive troughs. It represents the length of one complete wave cycle.

Frequency

Refers to how many complete wave cycles pass a givenpoint per unit of time, typically measured in hertz (Hz).

Node

A point where the wave has zero amplitude

Radio Waves, Microwaves, Infrared, Visible Light, UV Rays, X-Rays, Gamma Rays

Electromagnetic Spectrum in increasing frequency

Higher Frequency, Short Wavelength Higher Energy - Lower Frequency, Longer Wavelength, Lower Energy
