Formula for frequency (f)
f = v/λ
2
New cards
Formula for wavelength (λ)
λ = v/f
3
New cards
Formula for velocity (v)
v = f x λ
4
New cards
Example problem for finding velocity (v)
v = f x λ
Frequency (f) = 20 Hz
Wavelength (λ) = 2 m
20 Hz x 2 m = 40 m/s
5
New cards
Example problem for finding wavelength (λ)
λ = v/f
Velocity (v) = 500 m/s
Frequency (f) = 50 Hz
500 m/s / 50 Hz = 10 m
6
New cards
Example problem for finding frequency (f)
f = v/λ
Velocity (v) = 300 m/s
Wavelength (λ) = 10 m
300 m/s / 10 m = 30 Hz
