plz

can someone answer my question.

and second off, how does this vibration transfer to the surrounding atoms?(how does heat transfer)

like even if it has kinetic energy now, why doean't it just move in a straight line with some velocity? Why does it vibrate(oscillate around the same point rapidly)?

so when we give an atom energy, first off, why does it technically vibrate?

hey guys so i have a question about heat transfer and atomic vibrations

but, they are interfering ON the screen tho, not in our eyes so why do we see this?

hey, so in experiments like the YDSE, when light waves interfere ON the screen, we either see a bright spot or a dark spot right?

ohh ok thx!

wait but if its zero, it would become non defined not infinite?

ya that makes sense..

but if its infinite at center of mass, won't it be infinite everywhere according to gravity equation?

so some mass into 0 volume?

hey I so if black holes have infinite gravity, do they have 0 volume?

ok thanks

@JohnRennie can you elaborate?

since photon is actually just a packet of energy without mass...is it even possible for it to colllide with another particle and get deflected like particles with mass do?

how can we assume that a photon actually "collides" with the electron

hey so in Compton effect

but only some is successful

so all the light tries it

ohh now i get it

so even if we increase frequency, we are only talking about the 0.0005% of photons as the rest will still only do what they are doing

thats soo low

wth

so i guess we are talking about every photon IN that 5% of light right?

the rest go up in stuff like heating th metal surface

also i heard that only 5% of the light is used up in making photoelectrons tho

so the number of electrons that are ready to be ejected at threshold frequency is just so much that all the photons get used up?

ohh ok

but if the electron that bounces back has more energy then will his probablity of making through not increase?

ohh

so the rest just dont make it?

oh

fine so momentum is a vector and electron gotta conserve vector so it emits in same direction

ya that makes sense lol

im in college 1st year in my physics cycle rn

11th*

wow thats now what they taught me in 12th grade

what

but momentum isnt a vector

ya

thx

i overlooked the fact that v is a variable

oh i get it it was just a misunderstanding sorry

so how can we assume that?

but even if the variables y and x are related again, it doesnt mean they would be related that way right?

while solving homogeneous differential eqns, we assume that "y=vx"

soo i got a question

hey
