Express the number in our numeration system.

just take the area of the square and then the area of the circle then subtract the circle area from the squares area

step-by-step explanation:

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:

-81 -56 -27 0 81

step-by-step explanation:

0.038
