Find the distance between -4 and 10 on a number line.

14 units

Step-by-step explanation:

We have to take the absolute value of the measure in both directions, that is

| 10 - (- 4) | = | 10 + 4 | = | 14 | = 14

| - 4 - 10 | = | - 14 | = 14

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:
