high; wavelength
what is the result of constructive interference
a wave with increased amplitude
interference
when two or more waves combine to form a new one
compression
where particles are pushed together in a longitudinal wave
name the types of electromagnetic waves from longest to shortest
Radiowave, microwave, infared, visible light, ultraviolet, x-ray, gamma ray
a rhythmic disturbance that transfers energy through matter or space
wave
the amount of time it takes one wavelength to pass a point in seconds
period
examples of radio waves
wifi, tv, phones, MRI’s, radio stations
why are colors separated in a prism
the colors are moving at different speeds so they bend different
amplitude
the amount of energy carried by a wave
visible light waves
only electromagnetic waves we can see, different colors have different wave lengths
wave speed
how fast a wave travels
when a wave strikes an object and bounces off it
reflection
Waves carry ____ without carrying _____ from place to place
energy; matter
what are echos
reflected sound waves
name the types of electromagnetic waves from lowest to highest frequency
Radiowave, microwave, infared, visible light, ultraviolet, x-ray, gamma ray
examples of microwaves
used for cooking, doppler radar, and GPS
rarefaction
where particles are spread apart in a longitudinal wave
waves that are capable of transferring energy through a vacuum
Electromagnetic waves
What is the highest point of a wave called?
crest
Mechanical waves
waves that can only travel through a medium
period
the amount of time it takes one wavelength to pass a point in seconds
electromagnetic spectrum
the entire range of frequencies of electromagnetic radiation
matter through which a wave travels through; can be solid, liquid, or gas
medium
examples of infrared waves
night vision goggles, remote controls, and infrared photography
what type of wave is also called a compressional wave
longitudinal
what type of wave has matter in the medium moving back and forth at right angles
transverse waves
x rays are used to…
take pictures of bones to check for breaks/ fractures or in CAT scan
resonance
the occurrence of a vibrating object causing another object to vibrate a higher amplitude
compression
where particles are pushed together in a longitudinal wave
what is wavelength measured in
meters
_____ frequency = long _______
low; wavelength
space where there is no matter
ex. space
vacuum
vacuum
space where there is no matter
ex. space
reflection
when a wave strikes an object and bounces off it
where particles are spread apart in a longitudinal wave
rarefaction
refraction
the being of waves caused by a change in its speed as to ,press from one medium to another (BENDS) look different cause the speed changes
Wave
a rhythmic disturbance that transfers energy through matter or space
frequency
the number of waves that pass a given point in one second
ultraviolet waves are…
given off by the sun, used in light bulbs, to kill bacteria. and by the human body to make vitamin d
the number of waves that pass a given point in one second
frequency
how do you know the amplitude of a transverse wave?
the height of the wave, the distance of the trough to crest divided by 2
electromagnetic waves do not need a _______, they travel fastest through a ________ and slowest through _______
medium, vacuum, solids
medium
matter through which a wave travels through; can be solid, liquid, or gas
what waves transfer mechanical waves between electric and magnetic fields?
Electromagnetic
how do you know the amplitude of longitudinal waves
the compression
Mechanical waves travel faster through ______ mediums
warmer
waves that can only travel through a medium
mechanical waves
the amount of energy carried by a wave
amplitude
the lowest point of a transverse wave
trough
absorption
when an object is struck by a wave which goes into it, object absorbs the wave
diffraction
when an object causes a wave to change and BEND around obstacles
what kind of wave has matter in the medium moving back and forth in the same direction the wave is traveling
longitudinal
what color has the longest wavelength
red then orange then yellow….
name the types of electromagnetic waves from lowest to highest energy
Radiowave, microwave, infared, visible light, ultraviolet, x-ray, gamma ray
are sound waves or light waves larger?
sound waves
Waves can be either ____ or ____
longitudinal or transverse
