Waves Test Flashcards
How to waves transfer energy when they interact with matter
Energy causes particles to vibrate and collide with one another causing a chain reaction; particles go back to their original position
What do seismic, water, and light waves have
Energy
Particle motion in transverse and longitudinal waves
Perpendicular equals transverse
parallel equals longitudinal
Wave parts on transverse wave
Amplitude, crest, trough, wavelength, rest position
Parts on longitudinal wave
Compression, rarefaction, wavelength
Describe the relationship between wavelength energy and frequency
Wavelength down frequency up energy up
Wavelength up frequency down energy down
LLL longer lower less
Equation for wavelength frequency and wave speed
Velocity (meters per second) = frequency (hertz) x wavelength (meters)
Explain the cause of electromagnetic waves
Electromagnetic waves result when a charge particle is accelerated or decelerated
EM waves are created by the vibration of the electric charge
What are the seven parts of the electromagnetic spectrum
Radio, micro, infrared, visible, ultraviolet, x-rays, and gamma
Compare the seven parts of the electromagnetic Spectrum according to wavelength and energy
Radio long wavelength low-frequency low-energy
Gamma short wavelength high-frequency high-energy
What is reflection and example
Incoming light hits an object bounces off equal and opposite angle
Mirror reflects light
Refraction
When light waves change direction as they pass through medium
Straw appears to break in water
Diffraction
Bending, spreading of waves on obstacle
Rainbow
Absorption
Photons from light hit atoms and molecules, vibration occurs
Tanning
Scattering
Light bounces off object in different direction
Sky is blue
