For an independent study project, you design an experiment to measure the speed of light. you propose to bounce laser light off a mirror that is 51.0 km due east and have it detected by a light sensor that is 135 m due south of the laser. the first problem is to orient the mirror so that the laser light reflects off the mirror and into the light sensor. determine the angle that the normal to the mirror should make with respect to due west.

4.55 minute

Explanation:

51 km = 51000 m

the ray of light travels due east 51000 m , bounces back from reflecting mirrors  . The reflected light gets focused on a point 135 m south . Let the angle between incident light and reflected light be θ.

tanθ = 135 / 51000

θ = .1516 degree

= .1516 x 60 minute

= 9.09 minute

angle between incident ray ( east - west ) and normal = 9.09 / 2

= 4.55 minute Ans

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!
