Answer:
Infra red ranges from the upper end of the wavelength of visible light up to
1400
times that.
Explanation:
The wavelength of visible light ranges from
400
nm up to
700
nm.
The wavelength of infra red ranges from
700
nm (
7
×
10
−
7
m) all of the way up to
1
mm (
1
×
10
−
3
m).
So the range of visible light is about one octave while that of infra red is over ten octaves.
