Nanometer to Meter Conversions

This video tutorial explains how to convert between nanometers and meters using light equations. It covers the importance of converting nanometers to meters due to the speed of light being measured in meters per second. The tutorial provides a step-by-step guide on converting nanometers to meters by dividing by one billion and moving the decimal point left nine places. It also explains converting meters to nanometers by multiplying by one billion and moving the decimal point right nine places. Examples are provided to illustrate these conversions, including the use of scientific notation for clarity.
