10. which of the following statements is accurate?
a. sound waves passing through the air will do so as transverse waves, which vibrate vertically and still retain their horizontal
positions.
b. compressions and rarefactions occur throughout a transverse wave.
c. the wavelength of both traverse and longitudinal waves is measured parallel to the direction of the travel of the wave.
d. amplitude of longitudinal waves is measured at right angles to the direction of the travel of the wave and represents the
maximum distance the molecule has moved from its normal position.

Before coming into conclusion first we have to understand the nature of longitudinal wave and transverse wave.

The longitudinal wave is a type of mechanical wave in which the direction of wave propagation is parallel to the particle vibration.In such type of wave one will notice compressions and rarefactions.

Compressions are the high pressure zones where the particles are very close to each other and rarefactions are the low pressure regions where there is  large separation between particles. Hence a longitudinal wave is a series of compresions and rarefactions.

The wavelength of a longitudinal  wave is the distance between two successive compressions or rarefactions. Hence the wavelength is measured parallel to the direction of wave.  As the particle vibration is parallel to wave propagation ,so the amplitude of the wave is measured parallel to wave direction.

Transverse wave is such type of mechanical wave in which the particle vibration is perpendicular to wave propagation.Here crests and troughs are formed.

The distance between two successive crests or troughs are called wavelength which is measured parallel to the wave propagation. As the particle vibration is perpendicular to wave propagation,so the amplitude of the wave is measured perpendicular to the wave propagation.It is so because  amplitude of the wave is the maximum distance travelled by the particle from equilibrium position.

Out of the four options given in the question only the option 3 is correct .Other options are wrong as violate the nature of longitudinal and transverse waves.

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!
