Question

The wavelength of a certain laser is 0.66 microns, where 1 micron = 1 ⋅ 10-6 m.
What is this wavelength in nanometers? (1 nm = 10-9m)?  Please explain how you get th 6.6 x 10^2

First, explain in simple terms the power of ten, right or left.  If you move the decimal point to the right it means a negative power.  If you move the decimal point to left it is positive.
