Waves Flashcards
Amplitude
Is the maximum displacement of a point on the wave from its undisturbed position.
Wavelength
Is the distance between same points.
Frequency
Is the number of complete waves passing a certain point per second. Measured in Hz. 1Hz is 1 wave per second.
Transverse waves
The vibrations are perpendicular(90) to the direction of energy transfer. All electromagnetic waves, waves in water.
Longitudinal waves
The vibrations are parallel to the direction of energy transfer. Sound waves.
All waves can be…
Absorbed
Transmitted
Reflected
Absorbed waves
The wave transfer energy to the material’s energy stores.
Transmitted waves
The wave carries on traveling trough the new material.
Reflected waves
Where the incoming ray is neither absorbed or transmitted, but instead sent back.
Electromagnetic spectrum (order)
- Radio waves
- Microwaves
- Infrared
- Visible light
- UV
- X-rays
- Gamma rays
At the bottom of the EM spectrum, there is…
long wavelength and low frequency.
At the top of the EM spectrum, there is…
short wavelength and high frequency.
