What is a photon
What is a photon? how does it look like?
I think my concepts in atomic structure are weak because of poor clarity.
would be a lot helpful if someone gives me all the necessary details and information about these so called quanta

Note for OP
+solved @user to close the thread when your doubt is solved. Mention the user who helped you solve the doubt. This will be added to their stats.Hmm, it would be easier to explain if you understood the dual nature of radiation and matter I feel.

Yo man, nobody knows.
Lmao. True enough. But we do have theories don't we?
Boson-fermion studies. The Fermi-Dirac papers and Bose-Einstein papers specifically

हाँ ठीक है ये सब है तो, but that's what I was saying in the next audio, but answer to this question, short answer यही था.

and there are a lot of things- experiments has been done where you could see both the behaviors. तो आगै दोनों करता है तो। Let's accept it and move on and let's see how we can use it.
i have a whole lot of problem in understanding the concept of electromagnetic waves
Ah, that's my issue as well. I've been stuck on that chapter for a while now.
what really are these electromagnetic waves
Basically, a wave is when there is a series of changes in energy across a space right?
But energy is governed by the E-M fields right?
i just read its a to and fro motion of a particle around its mean position
So, when the field change as a function of time, there is a change in energy. That change in energy across the space is the wave.
That's basically an increase followed by a decrease in energy.
oh right
Think of it this way. You shake a charge really fast. Inverse square law says that field is also shaking very fast?
But field goes till infinity. So there is a sort of ripple effect.
thanks a lot bro but i think i understood a litttle
You're welcome. I think I understood a little more too.
thats great
Photon, in Newton's theory is like a particle that comprises light.
However in Quantum Mechanics, we know light is not just a particle, but both wave and a particle.
It's paradoxical, however, it works.
For example, take a look at the de-broglie equation that connects the particle nature and the wave nature.
\newline $\lambda = \frac{h}{p}$
\newline where p is the momentum given by $mv$ anda $\lambda$ is the wavelength.

oh okay bro
can u explain electormagnetic waves too?
Not in deptjh, cuz I've just started Electromagnetism.
As far as ik, when charged particles are at rest they produce a Electric field and when charges are in motion they produce a magnetic field.
However, there are two cases - constant velocity and accelerated motion.
When charges accelerate they release Electromagnetic Radiation. E.g. - Light.
They are both in form of waves and particles. (duality)
While in form of waves, they are coupled with a magnetic field and an electric field perpendicular to each other.
For more details, you can read some books on Modern Physics for fun. (if you get the time)
i think i need to read them rn
Oh I love this book. Beiser right?
Pretty sure it's Beiser
only if you have the time
Don't be like me who skipped chem and studied a lot of Physics books lol.
Same lol. I've been going through Feynman Vol.2 for the last month
I just noticed your profile pic
damn
I've just completed basic vector calc for maxwell equations :p
for understanding this shit for example
$$\nabla \cdot \vec{E} = \frac{\rho}{\epsilon}$$
Gauss' law
Keshav
yeah, the differential form
with the gradient operator
Yeah I'm done with vector calc
Might move onto tensor calc if I can manage it.
wait, do you need a lot of Tensor for E&M?
I skipped it in mechanics
Nope.
Only if you're working with quadrupoles iirc.
damn
hi guys i am currently studying in pw online batch i think the syllabus will complete in the next year(2025 starting) is it any good?
No clue. I think we should stop chatting in this thread now though
okay
+ solved @Keshav
