It's kind of wave :)

Answer 2

Then photon ?!

Answer 4

H:)

Answer 5

I want answer not sight .!

Answer 6

The \(quantum \ photons\) are not as easy as you think!You have to read a lot of books and visit many sites!Then you will give your answer...

Answer 7

haha :)

Answer 8

I think you don t want to answer me :)

Answer 9

No!we show the way to people here!
and I \( \Huge \color{red}{can't}\) give you the answer...

Answer 10

Ok. you can t .!! Just it !!!

Answer 11

@E.ali what u think the answer could be ?

Answer 12

What about you ?

Answer 13

There are some experiments that can not be explained by considering light as wave and also there are some other experiments that tells that light is wave. And now we know that it's not either wave or particle but it's both wave and particle. And which nature you are going to encounter that depends on the experiment you are doing. May sound strange and not convincing but you have to accept it.
There are some very classic experiment in history that leaded to quantisation of energy.
for example, Black body radiation, photoelectric effect, Compton effect etc. It was seen the the interaction or exchange of energy is not continuous as in the case of typical wave interaction but rather it was found discrete and instantaneous. Not only this there are so many arguments in the favor of particle nature of light. If you are interested you must read De Brogile's Ideas for dual nature of matter.

Answer 14

@wini_boson , It was great!
i want to know more about this and you said "If you are interested you must read De Brogile's Ideas for dual nature of matter"
how can I know more about this book?do you know any sites about this?

Answer 15

What book ?

Answer 16

not book

Answer 17

"his Ideas"

Answer 18

Hey its basic of Science @PFEH.1999
hey nice paragraph by @wini_boson

Answer 19

sorry, it's not a book it's a hypothesis made by De Brogile. You just google "de broglie dual nature of matter".

Answer 20

Thank you very much :)

Answer 21

you cant ask my question yet !!!

Answer 22

thanks:) @chmvijay

Answer 23

its photoelectric effect is that right ?

Answer 24

yep

Answer 25

@E.ali , What exactly is your question? We gave you alot of information but you are still saying "You didn't answer my question"!

Answer 26

Haha .
My question answer is one word .
yes or no ?!!!

Answer 27

you think "What exactly defines the photon nature of light?" is a Yes/No question?

Answer 28

What you mean by 'yes or no'?

Answer 29

its good you both @PFEH.1999 and @E.ali should read the fundamental of this subject

Answer 30

yes,I will read it ;)
but do you know a good book of this subject?

Answer 31

first read the ur school TEXT book then i will give u a book on the following subject OK @PFEH.1999

Answer 32

Is the light photon or wave or both of them ?!

Answer 33

ok...
I found this book,is it good?

Answer 34

@E.ali , both of them
@wini_boson said...

Answer 35

both of them

Answer 36

@ all : how ?

Answer 37

If you read it,you wouldn't ask this question:
"There are some experiments that can not be explained by considering light as wave and also there are some other experiments that tells that light is wave. And now we know that it's not either wave or particle but it's both wave and particle. And which nature you are going to encounter that depends on the experiment you are doing.

Answer 38

nice time pass u both are doing here haaa

Answer 39

:D
@chmvijay , was that book - that I attached - good or not?

Answer 40

good one :)

Answer 41

The concept of a photon came up because it was found that in interactions of electromagnetic waves with matter a discrete amount of energy equal to hv ( where h is Planck's constant and v is the frequency of the radiation) is transferred. This bundle of energy is called a photon.
