Measuring waves Flashcards
1
Q
complete the sentence
the higher the frequency of a wave, the…
A
shorter the wavelength
causes the peaks to be closer together
2
Q
what is the equation for the speed of the waves?
A
c = distance travelled in one cycle / time taken for one cycle
= f λ
3
Q
What is the phase of a vibrating particle at a certain time?
A
fraction of a cycle it has completed since the start of the cycle
4
Q
What is the phase difference between two particles vibrating at the same frequency?
A
the fraction of a cycle between the vibration of the two particles, measured in degrees or radians
where 1 cycle = 360° = 2π radians
5
Q
What is the equation for the phase difference in radians?
A
2πd / λ
d = distance
