Question

Red light has a wavelength of about 700 nm. What is this measurement in meters?

Answer 1

To convert a wavelength from nanometers (nm) to meters (m), you can use the following conversion factor:

1 nm = 1 × 10^(-9) m

Given that the wavelength of red light is approximately 700 nm, we can convert it to meters as follows:

700 nm * (1 × 10^(-9) m / 1 nm) = 700 × 10^(-9) m

Simplifying the expression:

700 × 10^(-9) m = 7 × 10^(-7) m

Therefore, the wavelength of red light, approximately 700 nm, is equal to 7 × 10^(-7) meters.
