let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:

i'm sorry mate, but i am not seeing any figures. i am unable to solve this for you.

answer: 12,000
