A “particle of light” (photon) can be considered a bundle of waves. The relationship between the wavelength (λ) and frequency (f) of light is: λ f = c . Light visible to our eyeballs has wavelengths between

    This may sound surprising at first, but since the speed of light in air is a little lower than in a vacuum, it does not violate any law of physics. In 1934, Russian physicist Pavel Cherenkov proved that particles that move faster than light in air generate a kind of optical shock wave - a bluish glow known as Cherenkov light.
