Answer:
[tex]7.00 \cdot 10^{-7} m - 1\cdot 10^{-3} m[/tex]
Explanation:
Infrared radiation has wavelength in the range between 700 nm and 1 mm. Lets' convert these values into scientific notation, keeping in mind that:
[tex]1 nm = 10^{-9} m\\1 mm = 10^{-3} m[/tex]
Let's start from the lower value, we have:
[tex]700 nm = 700 \cdot 10^{-9} m = 7.00 \cdot 10^{-7} m[/tex] (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:
[tex]1 mm = 1 \cdot 10^{-3} m[/tex]
So, the range of wavelength of infrared radiation is:
[tex]7.00 \cdot 10^{-7} m - 1\cdot 10^{-3} m[/tex]
