Homework Statement

the wavelength of a laser is 720 nanometers. convert the wavelength to meters.

Homework Equations

i am not sure of an equation that will help me.

The Attempt at a Solution

this question was on a quiz i had recently and i got it wrong. i just divided by 1000 as a complete guess.

1 meter = 10^9 nanometers I believe

thank you! as i think about it now my teacher did remind me that always add 10^9 after the wavelength.

Its 10^-9 I believe.

As a scientist, it is important to understand the units of measurement and how to convert between them. In this case, the unit of measurement for the wavelength of a laser is nanometers, which is a very small unit of length. To convert nanometers to meters, we need to use the conversion factor 1 nanometer = 1x10^-9 meters. This means that to convert 720 nanometers to meters, we need to multiply 720 by 1x10^-9, which gives us a wavelength of 0.00000072 meters. It is important to be familiar with common conversion factors and to double check your calculations to ensure accuracy.
