<PRE><B>Question 119479</B>
A meter is equal to 1 000 000 microns. Blue light has a wavelength of 4.7*10^-1 micron. Express this wavelength in meters.
Using the conversion unit (1 meter/10^6 microns) you get the following:
-------------
4.7*10^-1 micron(1 meter/1,000,000 micron) 

= (4.7*10^-1/10^6)meters

= 4.7*10^-7 meters
