Resumo de Recurso
Waves
Types
Transverse
The oscillation is perpendicular to the energy transfer.
e.g. Light.
Longitudinal
The oscillation is parallel to the energy transfer.
e.g. Sound.
Electromagnetic
Can travel through anything (i.e. vacuums).
Mechanical
Requires matter to exist.
Wave Length
The distance between two equal points.
Amplitude
Represents the energy.
Hertz (Hz)
Waves per second (frequency)
Equations
Wave Speed = Frequency x Wave length
m/sec = Hz x m
Properties
Reflection
Angle of incidence = angle of reflection.
Refraction
Waves change direction when crossing between different media.
This is because the light ray enters the block earlier on one side meaning that this side slows.
Into higher densities, the light slows.
Diffraction
When the waves spread out after passing through a gap.
Perfect diffraction occurs when the gap is the same size as the wavelength.
This will produce a semicircular pattern.
Doppler Effect
When the sound source is moving away...
The pitch lowers.
The wavelength increases.
The frequency decreases.
When the sound source is moving closer...
The pitch rises.
The frequency increases.
The wavelength decreases.
Position alone has no impact.
Red-Shift
Light from distant stars/galaxies is shifted towards the red end of the spectrum due to a longer wavelength.
This shows that the star/galaxy is moving away.
The further away the star/galaxy is, the greater the red-shift.
Proves that the universe is expanding.
