All of these questions are true or false answers but, i am unsure if i am correct in my answers. Any help would be appreciated.

Homework Statement


1. When a wave reaches a boundary between two media and some or all of the wave bounces back into the first medium, this is known as reflection.

2. Your eye cannot ordinarily tell the difference between an object and its virtual image.

3. When light waves move from one medium into a medium in which they travel more slowly, the light wave is bent away from the normal.

4. The separation of light into colors arranged according to their frequency is called diffraction.

5. A camera forms a virtual image on film.

6. The layer of tissue at the back of the eye is the iris.

7. In a far-sighted eye, light focuses in front of the retina.

8. The bending of a wave around an obstruction is called refraction.

2. The attempt at a solution

ok thanks mate
 

1) Is it possible for a statement to be both true and false in physics?

Yes, in certain situations, a statement can be both true and false in physics. This is known as a paradox, where seemingly contradictory statements can both be true in different contexts.

2) How do scientists determine if a statement is true or false in physics?

Scientists use the scientific method to determine if a statement is true or false in physics. This involves formulating a hypothesis, conducting experiments, and analyzing data to reach a conclusion.

3) Can a false statement in physics be proven true in the future?

Yes, scientific knowledge and understanding are constantly evolving. A statement that was once believed to be false in physics can be proven true in the future with new evidence and advancements in technology.

4) Are all scientific theories in physics either true or false?

No, scientific theories in physics are not simply labeled as true or false. They are constantly being tested and refined, and can be considered more or less accurate depending on the available evidence and current understanding.

5) How can I check the accuracy of a statement about physics that I come across?

You can check the accuracy of a statement about physics by researching reputable sources, such as scientific journals and publications, and consulting with experts in the field. It is important to critically evaluate information and not rely on a single source.
