SCIENCE UNIT 4 VOCAB Flashcards
(21 cards)
repeating disturbance that transfers energy as it travels through space or matter
wave
distance between one point on a wave and nearest point just like it
wavelength
measure of size of disturbance of a wave, related to energy it carries
amplitued
measure of size of disturbance of a wave, related to energy it carries
amplitude
highest point on a transverse wave
crest
denser region of a longitudinal wave
compression
lowest point on transverse wave
trough
matter through which wave travels
medium
horizontal row on periodic table amount of time it takes one wavelength to pass a fixed point, expressed as seconds
period
number of wavelengths that pass a fixed point each second, expressed in hertz
frequency
a wave that can only travel through matter
mechanical wave
wave in which matter in medium moves at right angles to direction of the wave, has crests and troughs
transverse wave
wave in which matter in medium moves back and forth along direction move travels
longitudinal wave
bending of a wave caused by change in its speed as it travels from one medium to another
refraction
less dense region of longitudinal wave
rarefraction
bending of waves around a obstacle can also occur when waves pass through narrow opening
diffraction
process of two or more waves overlapping and combining to form a new wave
interference
process by which an object is made to vibrate by absorbing energy at its natural frequencies
resonance
point in standing wave which the interfering waves always cancel
node
a wave pattern that forms waves equal wavelengths had amplitude but traveling in opposite directions continuously interfering with each other’s, doesn’t appear to be traveling
standing wave
waves created by vibrating electric charges of vibrating electric and magnetic fields, and can travel trough matter
electromagnetic wave
