You are going to mix a gallon bucket of water cleaner. the instructions ditect you to mix 1 part cleaner to 3 parts water. how much cleaning soulution will you need?

what's that

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:
