True or False three questions on science.?

Question

1. The sun travels around the earth daily.
2. Apart from the hills and valleys,the surface of the earth is flat.
3. Optical instruments make objects appear intrinsically brighter than when they are viewed by the naked eye.
The first to answer correct 1-3 true or false gets the points.

You will get the points for being first to say all are false after the 24 hr waiting period.
The first two are classic examples of how humans were long decieved by our lying eyes.
The third statement ,another example of how our eyes mislead us, is generally still believed.This,despite the widely published fact that no optical instrument is capable of transmitting more than 95 percent of light that enters in.Actually ,the telescope view of an object is always dimmer than the direct view.Our eyes deceive us regarding image brightness because of a tunnel vision effect,that occurs whenever the field of view is surrounded by contrasting areas of darkness,such as the blackened interiors of a optical instrument.
Good job

Answer 1

All are false if viewed literally.

Answer 2

1. False the Earth travels around the Sun yearly, and rotates along this path daily. I suppose you could argue that it is a matter of perception but really everything is moving around some obscure point.

2. False there are plateus and the like that affect terrain, but even accounting for those, the Earth itself is round.

3. False most optical instuments would acutally make things appear more dim because some light would be scattered before it could reach our eyes by the large molecules in the instrument. Nothing can really make something brighter, an object only reflects what it reflects, but it can shift the light to be more yellow and make it seem more bright. Interestingly our eyes themselves make many things seem brighter or bigger than they are. When we look at a line or seam between a black and a white region there are some light receptors that get both a "black" and a "white" message... they automatically go with white because they can only give one message or the other to the brain... this is why white seems to glow or bleed against black.

Answer 3

1. No, but perhaps we could make an argument for yearly based on perspective.
2. If space is curved, then perhaps the earth is flat without hills or valleys, or maybe it's even flat with them.
3. I have never worn clothes on my eye so I've only seen stars naked with and without a telescope.

Answer 4

1. F
2. F
3. Not enough information to determine. Some optical instruments are designed to reduce the light like sun shades and some enhance the light like star scopes the military uses for snipers at night, unlike thermal imaging the gather light and transmit it to the eyes.
