When an ophthalmologist uses an ophthalmoscope to look into your eye he sees the following view of the retina
In the center of the retina is the optic nerve, a circular to oval white area measuring about 2 x 1.5 mm across. From the center of the optic nerve radiates the major blood vessels of the retina. Approximately 17 degrees (4.5-5 mm), or two and half disc diameters to the left of the disc, can be seen the slightly oval-shaped, blood vessel-free reddish spot, the fovea, which is at the center of the area known as the macula by ophthalmologists.
The first statement, “We never get to see the far side of the moon” is <u>true</u> among all the statements given.
Explanation:
We only see one side of the moon from Earth, which is commonly referred to as the “near” side of the moon. We are able to see this side through our naked eyes due to the sunlight reflecting of the surface of the moon.
However, this is not to say that the far side of the moon does not receive sunlight at all. It does receive, but it’s just that the far side of the moon never faces the Earth and hence we never see it.
Having said that, the other statements are false. The near side itself goes through weeks of darkness, where it is not lit up by the Sun. The moon has its own axis upon which it rotates. And the moon orbits the Earth and one full rotation takes about 28 days.
