Answer this one please

JL

Step-by-step explanation:

if JK is the facing side and KL is the hypotenuse then JK is the adjacent side

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:

umm you say your want to . but you do know that this is the mathematics.
