Used the ueendigram to illustrate the information below U=(1,2,3,10) Q=(1,2,3,6,8)
P=(2,4,5,7) R=(1,2,4,6,9)

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:

1/8 is left? add a bit more info plz

the answer is $23.63
