Answer 2

A) 1 × 10–7 m

Step-by-step explanation:

Hello,

Visible light is characterized by the formation of the colors we can see, in fact, that is why it is called visible light. Moreover, the wavelength regarding it is about 100 nm which are equal to:

`100nm*(1m)/(1x10^9nm)=1x10^(-7)m`

Thus, the answer is A) 1 × 10–7 m.

Best regards.
