Answer:

the length of the photon's wavelength is 0.00000072 meters.

Step-by-step explanation:

To convert a length from nanometers (nm) to meters, you need to divide the length in nanometers by 1 billion (since there are 1 billion nanometers in a meter).

Given wavelength: 720 nanometers

Length in meters = 720 nm / 1,000,000,000 (since 1 billion nanometers = 1 meter)

Length in meters = 0.00000072 meters
