Waves Flashcards
1
Q
States that the frequency of a wave equals the reciprocal of its period of oscillation.
A
f = frequency in Hz
T = period in s
Used to convert between frequency and period of a wave.
2
Q
Formula for the speed of a wave
A
v = speed in m/s
f = frequency in Hz
𝜆 = wavelength in m
3
Q
Formula for the energy of a photon
A
E = energy of a photon in J
h = Planck’s constant = 6.626 x 10-34 kg m2 s-1
f = frequency in Hz
