Properties of Waves Review Flashcards
Transverse waves carry energy ________ to the motion of the wave.
Perpendicular
The highest point of the wave
Crest
The lowest point on the wave
Trough
The distance between a crest and a crest or a trough and a trough
Wavelength
The distance between the midpoint to a crest or the midpoint to a trough
Amplitude
These waves carry energy parallel to the motion of the wave
Longitudinal
The part of the longitudinal wave where the particles of the medium are closer together
Compression
The part of a longitudinal wave where the particles of the medium are further apart
Rarefaction
The distance between compressions or the distance between rarefactions
Wavelength
Relates how close together the particles in the medium are at the compressions of the wave
Amplitude
What affects the amplitude of a wave?
The energy a wave carries
The more energy a wave carries equals a higher amplitude. True or False
True
The range of wavelengths of electromagnetic waves
The electromagnetic spectrum
Gamma rays have the longest wavelength. True or False
False; the shortest
Which electromagnetic waves has the longest wavelength?
Radio waves
The number of wavelengths that pass a fixed point in a second
Frequency
Hertz is used for the expression of what?
Frequency
The amount of time it takes for a wavelength to pass a certain point
Period
Frequency (Hz) x Wavelength (m) =
Speed of a wave
Equations
Wavelength =speed/frequency
Equations
Frequency=speed/wavelength
Light waves travel faster through
Gases and liquids
Sound waves travel fastest through 1.______, slower through 2.______, and slowest through 3.______.
- Solids 2. Liquids 3. Gases
A higher temperatures, particles bump into each other more often, increasing the chances of energy transfer. True or False
True (Temperature of Medium)
