Energy waves test Flashcards
(22 cards)
What is frequency
Number of waves passing a point in a given time
What Is wavelength
DISTANCE between two neighboring crests or troughs
what is Amplitude
HEIGHT of a transverse wave
what is a wave
a disturbance that transfers energy from place to place
what is a transverse wave
Particles of the medium move at right angles to the direction of wave motion BIG WAVES
What is a longitudinal wave
Particles of the medium move parallell to the direction of wave motion
what is an electromagnetic wave
Electromagnetic waves are a form of radiation that travel though the universe. They are formed when an electric field (Fig. 1 red arrows) couples with a magnetic field (Fig. 1 blue arrows).
Amplitude is..
height
crest
the part you measure from/; the tip
Mechanical wave
Transfers energy through some of the matter EX water
Longitudinal wave
One HZ= one wave per second
Trough
opposite side of crest
Medium
Material witch waves transfer
compression
Particles are close together
rarefraction
particles are far apart
Intensity
The amount of energy n a sound wave
How do particles of a medium behave when a wave travels through
Vibrate in place
what does a wave look like that has a high/low frequency or pitch
High frequency has smaller faster waves and low frequency has slower longer waves
what is the relationship between frequency and pitch
The frequency of a sound wave is associated with our perception of that sound’s pitch.
what is the relationship between loudness and amplitude?
Greater the amplitude, greater is the loudness.
what is the speed of waves through different materials (solids liquids gasses)
Solids are packed together tighter than liquids and gases, Sound travels faster in liquids than in gases because molecules are more tightly packed, in gasses they are all freely
what is the difference between transverse and longitudinal waves
transverse has BIG waves, Small waves longitudinal
