"Does" => singular verb.
"Quanta" => plural noun.

Only proper nouns are capitalized in English.

"Do light quanta have mass?"

1.

According to Michelson-Morley experiment light
quanta moves with constant speed: c=1.

"Quanta" => plural noun.
"Moves" => singular verb.

In English, an astonishing number of trasitions
sound clunky without articles to decorate the nouns.

In English, prefatory phrases are usually set off
by commas from the main sentence body.

"According to the Michelson-Morley experiment, light
quanta move with constant speed: c=1."

And that is only true in a strange system of units.
In the MKS system, the speed of light is nearly
300,000,000 meters per second.

The physicists say it is result of lack mass at
light quanta.

Your pronoun "it" has no clear referent.

Again, you often need to use articles to make
English sound correct.

You don't want "at", you want "of".

"The physicists say [that constant speed?] is a
result of the lack of mass of light quanta."

Well, what you call "light quanta", and most people
call "photons" lack only rest mass. They do have a
"mass of motion" associated with their energy, and
since different photons have different energies,
they also have different masses.

2.
According to GRT gravitation bends light quanta.

According to physical observation, as well.

This fact was tested by experiment and showed that
Einstein was right.

But to be bend from the straight line light quanta
must have a mass.

For "be bend" you wanted "be bent".

Unless you are talking about a _specific_ straight
line, the appropriate article is "a", the indefinite
article, not "the", the definite article.

Again, set off prefatory phrases with commas.

Here, you got the subject and verb numbers to agree.

"But to be bent from a straight line, light quanta
must have a mass."

3.

If light quanta has mass when according to SRT,
moving with constant speed c=1 its mass become
infinite. That is impossible.

And here, you did not get the subject and verb
numbers to agree.

"Quanta" => plural noun.
"Has" => singular verb.
"Its" => singular possessive pronoun.
"Become" => plural verb.

You want "then" where you used "when".

Remember commas.

"If light quanta have mass, then according to SRT,
moving with constant speed c=1, its mass becomes
infinite. That is impossible."

Well, you suffer from confusion between "rest mass"
and "mass of motion". What you claim is true for
rest mass, but since photons don't _have_ rest mass
(because they don't exist in a state of rest, I
suppose), that nonexistent mass doesn't become
infinite at the speed of light.

School’s question: What is Light Quanta?

"What are light quanta?"

A packet of electromagnetic radiation containing
energy and moving at the speed of light. It is best
described by Maxwell's equations, but understanding
those equations requires quite a bit of education.

======================= . .

P.S.

On my opinion without to understand what " The Law
of Conservation and Transformation of Energy/ Mass"
means according to single light quanta this question
connot be solved.

Perhaps you should restrain yourself from having
opinions until you have sufficient education to
justify having opinions, and just for the time
being, accept what people who do have sufficient
education tell you to be the case?

( And , please, don’t forget about dualism of
light quanta: as a particle without mass ( ?), and
a wave as a - ? )

================= . .

Would it be a good guess that English isn't among
your first few languages?

And, was there any particular point in you posting
such a question to a newsgroup where discussion of
issues of origins, not issues of pure physics, are
on topic?
