Which is a common way for a scientific calculator to show the number below?
8.1 x 102
A. 2 x 108.1
B. 2.18
C. 2.1E8
D. 8.1E2

step-by-step explanation:

it's is b

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:
