Which color of light has a wavelength of
5.0 × 10^–7 meter in air?
(1) blue (3) orange
(2) green (4) violet

Green              

Explanation:

We have given that, the wavelength is in air. We have to write the color that corresponds to this wavelength.

The given wavelength lies in visible region of spectrum. The visible region lies in between 380 nm to 740 nm. The wavelength of violet color is least while the wavelength of red color is maximum.

The above wavelength corresponds to green color. Its wavelength lies from 500 nm to 565 nm. Hence, teh correct option is (c) " green ".

explanation:

no diagram was provided, but i'm guessing it's the one i've attached to my answer.

here, a mechanical force turns the rod.   this generates an electric current in the coil, which powers the bulb.
