How far is 650nm?

Answer 1

That's actually fairly meaningless, 1nm is one nanometre, there are one billion (1 000 000 000) nanometres in one metre. There are 1 609 metres in one mile. The number of nanometres in one mile is to big to be really meaningful.

Answer 2

One nanometer is 1x10-9 meters, so 650 nanometers is 6.5x10-7 meters.

Algebraic Steps / Dimensional Analysis Formula 650 nm*1 m

1000000000 nm=6.5e-7 m

Answer 3

650 nm is the wavelength of the light. The wavelength determines the color. 650nm light is red.

Answer 4

650*10-9 meter
