Infra red ranges from the upper end of the wavelength of visible light up to $1400$ $1400$ times that.

Explanation:

The wavelength of visible light ranges from $400$ $400$ nm up to $700$ $700$ nm.

The wavelength of infra red ranges from $700$ $700$ nm ( $7 \times 10^{- 7}$ $7xx10^-7$ m) all of the way up to $1$ $1$ mm ( $1 \times 10^{- 3}$ $1xx10^-3$ m).

So the range of visible light is about one octave while that of infra red is over ten octaves.
