What you need to know is how a millimeter to one nanometer refers to your problem to fix.
1 mm = 1,000,000 nm
Therefore, 001 mm = 1000 mm = 002 nm and 2000 nm
The rest should be easy for you.
2000 / 475 =
Blue light ranges from 400 nm to 480 nm. When the thickness of the plastic bag. Oo2mm, which is about 2000Nm so ....
.000002/.000000400 = 5 and .000002/.000000480 = 4.16
So x is the thickness ...
4.16 \\ \\ \\ \\ \\ \\ \\ \\ u0026lt, x \\ \\ \\ \\ \\ \\ \\ \\ u0026lt, 5
Thus, the units of eight ...
1 nm = 10 ^ -9 meter, 1 mm = 10 ^ -3 m
N = 002 mm / 475nm
= .002 X 10 ^ 6 nm / 475nm
~ 4,2
