Answer: Light passes through the front of the eye (cornea) to the lens. The cornea and the lens help to focus the light rays onto the back of the eye (retina). The cells in the retina absorb and convert the light to electrochemical impulses which are transferred along the optic nerve and then to the brain.
Explanation:
When light rays reflect off an object and enter the eyes through the cornea (the transparent outer covering of the eye), you can then see that object. The cornea bends, or refracts, the rays that pass through the round hole of the pupil.
Scientists use models to study atoms, Because atoms are very tiny, and almost impossible to cut open and look inside.. And the center of an atom is the nucleus and that is ever smaller.
Answer:
464.8 nm
Explanation:
The second wavelength of light can be calculated using the next equation:
<u>Where:</u>
<em>λ : is the wavelength of light</em>
<em>x: is the distance from the central maximum</em>
<em>d: is the distance between the spots </em>
<em>L: is the lenght from the screen to the bright spot</em>
For the first wavelength of light we have:

(1)
For the second wavelength of light we have:

(2)
By entering equation (1) into equation (2) we have:

Therefore, the second wavelength is 464.8 nm
