Do electromagnetic waves need a medium to travel thorugh it like mechanical waves?

NO, electromagnetic waves dont need it. The changing fields from electromagnetic waves make it so it doesn't need it.

what are photons

electromagnetic waves can behave as waves and particle

beginning of electromag spectrum

longer wavelength, lower frequency, lower energy

ending of electromag spectrum

shorter wavelength, higher frequency, higher energy

refraction does..

change speed of medium

deffraction does..

changes direction of medium

constructive is

louder , when 2 waves come together

destructive is

no sound , when 2 or more waves form opposite osmething idk lol but it has no sound

resonnance is

process where an object is made to vibrate at its natural frequency

refraction is

the bending of waves

a measure of how long the wave is , taken from one wave to the same point on the next wave

wavelength

the human perception of intensity

loudness

a term related to frequency that increases as frequency increases

pitch

a measure of the energy passing through an area in a set amount of time

intensity

the number of waves per second

frequency

the matter a wave moves through

medium

the height of a crest, the depth of a trough, the density of a compression and / or the sparseness of a rarefaction

amplitude

which wave would travel the fastest in a vacuum? light or sound?

light because its electromagnetic meaning itll travel through vacuum faster than mechanical.

period is..

amount of time it takes one wavelength to pass a point

transverse waves are..

matter in the medium moves back and forth at right angles to the direction that wave is travelling, they are snart waves

longitudinal waves are..

matter in the medium moves back in forth in same direction it travel, they are ocmpression waves
