Afish swims 10 cm from the front wall of an aquarium that is 35cm wide. the front wall of the aquarium is glass with negligible thickness, but the back wall is a plane mirror. a person looks through the front wall and watches both the fish and its reflection in the mirror. part a: what is the apparent distance from the front wall of the aquarium to the fish? part b: what is the apparent distance from the front wall of the aquarium to the image of the fish in the mirror?

El problema es un caso generalmente tipico en optica concerniente a Apparent depth vs real depth

We see the objects closer than their real depth to the surface. We see objects only if the rays coming from them reaches our eyes.

The equation is given by,

Where,

Apparenth depth

Real depth

Refractive index of the medium of object

For water is equal to 1.33

I attach an image of the theory that could help clarify the measurements.

We have,

Therefore the apparent distance between the front wall of the aquarium to the fish is 7.5cm

B) The distance between fish and mirror is given by,

So we have that real distance from the front wall of to image of fish is

Applying our equation we have that,

Therefore the apparent distance from the front wall of the aquarium to the image of the fish is 45.1cm

quantum mechanics or quantum physics is physics of very small objects (particles) and physical entities.

quantum physics has some parallels to our macro world and some pretty unique ideas which theoretically and mathematically proven to be true even though we will never be able to access them because of our size.

there are many types of particles: subatomic, elementary etc.

subatomic means they are smaller than atom, elementary means they are at the very basis of everything.

subatomic particles are for eg. protons, neutrons but not electrons.

elementary particles are categorised into 3 groups by what they do.

these 3 groups are quarks, leptons and bosons.

light for example is a particle more precisely a photon a part of leptons.

proton (subatomic particle) is made out of 2 up quarks and 1 down quark each of these has a fractional charge like . (i crazy)

most famous scientist who contributed to this physics are:

the topic itself us understand a lot and will probably be vastly used in the future (quantum computers, understanding the big bang,

we also must not forget quantum effects like:

and there is more. but probably too much for this answer to be consistent due to my average understanding of this topic.

hope this you understand quantum mechanics a little more. i'm not an expert in the topic (so don't be like wth if you are an expert) but i'm very interested in it.

anyways quantum physics is a very hard topic (harder than physics (perhaps)) therefore searching for every information there is about it and learning it is unfortunately impossible (you can only specialise into 1 - 3 things or more (perhaps

have fun and i wish you luck!
