Wavelength calculated using speed of light (299,792,458 m/s)
Conversion Formulas
Hz → kHz: kHz = Hz ÷ 1000
MHz → GHz: GHz = MHz ÷ 1000
Wavelength = c ÷ f
c = 299,792,458 m/s (speed of light)
FAQ
What is frequency?
Frequency is the number of cycles per second, measured in hertz (Hz). It describes how often a periodic phenomenon repeats.
How are frequency and wavelength related?
Frequency (f) and wavelength (λ) are inversely proportional: λ = c/f where c is the speed of light (299,792,458 m/s).
What is the electromagnetic spectrum?
The electromagnetic spectrum ranges from radio waves (low frequency, long wavelength) to gamma rays (high frequency, short wavelength).
