Step-by-step explanation:

7/8 - 1/8 = 0.75

0.75 = 3/4 in simplest form

7/8-1/8= 6/8
you don't subtract the denominators because they're the same
6 and 8's common factor is 2
so you divided 2 by 6/8 and you get 3/4
the simplest form is 3/4

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:
