ฮป = v / f
f = v / ฮป
T (period) = 1 / f
ฮป = v / f, where ฮป is wavelength (m), v is wave speed (m/s), and f is frequency (Hz).
Visible light ranges from ~380 nm (violet) to ~700 nm (red). The speed of light is 3 ร 10โธ m/s.
In air at 20ยฐC (v=343 m/s): ฮป = 343 / 440 โ 0.780 m (78 cm). This is the musical note A4.
They are inversely proportional: double the frequency and the wavelength halves (at constant wave speed).
