Period, frequency, wavelength and simple pendulum.
Physics
Frequency from period
f = 1 / T→PhysicsPeriod from frequency
T = 1 / f→PhysicsWavelength
λ = v / f→PhysicsSimple pendulum period
T = 2π√(l / g)→PhysicsWave angular frequency
ω = 2π/T→PhysicsWave number
k = 2π/λ→PhysicsWave phase difference
Δφ = 2πΔx/λ→PhysicsStanding-wave resonator length
L = nλ/2→PhysicsWave intensity from amplitude
I = A²→
