Waves introduction Flashcards
1
Q
What is a wave?
A
A wave is a method of transferring energy and information between two places.
2
Q
Describe how a longitudinal wave looks like
A
In a longitudinal wave, the oscillations of a particle are parallel to the direction of the energy transfer. ( e.g sound wave)
3
Q
Describe how a transverse wave looks like
A
In a transverse wave, the oscillations of a particle are perpendicular to the direction of energy transfer. (e.g water wave or a light wave)
4
Q
What is the wavelength?
A
The wavelength is the distance between to identical parts of a wave.
5
Q
What symbol do we give to the wavelength?
A
lamda λ
6
Q
What is the amplitude?
A
The amplitude is the maximum displacement of a wave from it equilibrium position.
7
Q
What is the frequency?
A
The frequency is the number
