How can i solve this: |n| ≥ n i know it's infinite solutions, but why? and also what about when |n| ≤ nwhy is it only zero and infinite positive solutions?

hope this !

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:

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:
