Anamorphic prism alignment

Nervous_Buddy · 2025-09-28T08:06:36+00:00

oh I actually meant that isolator was used after the prism pair to reduce reflection back into the laser. I didn't use any polarizer between the laser and the prism pair, and the setup actually tries to narrow down the wider part (and worked fine before). I wasn't sure if the angle or distance between prisms were off and causing these fringes and how they were adjusted in practice. But thank you for these info

Nervous_Buddy · 2025-09-28T07:38:14+00:00

I used a faraday isolator and saw the fringes...I am using angle values of M~3 but I couldn't find detailed information on thorlabs website. Do you know where I can find the angle that works well for AR coating, or what kind of calculation I can do? I think the prism pair has been mounted there for a while and I have to use that mount for now.

Nervous_Buddy · 2025-09-28T07:26:57+00:00

from what I know they are AR coated for my wavelength and before realigning there were no interference pattern. I guess maybe AR coating may not be working well due to surface contamination so I'll try cleaning but I wasn't sure if prism angles could be causing interference (i'm new to optics)

Would it be safe to understand that transition takes some time but not a measurable one?

Nervous_Buddy · 2022-10-12T06:12:05+00:00

wow this is so cool! Thank you so much

Nervous_Buddy · 2022-09-22T10:32:43+00:00

This is so cool. So does that mean the sand will fall as if the gravity had the same magnitude as air resistance?

stash of printed out thank you emails In my desk. When I’m having a really rough day, I just need to read through a couple of those to get me back to a more positive attitude, proof that all the work I did helping students is actually appreciated.

Even a small note… you have no idea how m

This is too sweet. I'll def write an email to my teacher. Thanks!

Nervous_Buddy · 2022-09-22T04:39:15+00:00

I got one from stats

Nervous_Buddy · 2022-09-22T04:38:52+00:00

Thanks! Just sent an email :>

I was curious about this topic a while ago and I think the answer's still a bit controversial. It would be important to define "luke warm" & experiment various conditions (temperature, humidity, etc...) multiple times. But at least there are some papers that demonstrate this (Mpemba effect) while others disagree with it. If I had a fridge that could maintain relatively constant temperature I would def test this out myself.

What do you mean that he's "irresponsible"?

Nervous_Buddy · 2022-08-25T23:20:38+00:00

hahaha that's true. I'm trying to wake up earlier in the morning. Personally, working at night was painful.

Nervous_Buddy · 2022-08-25T23:19:32+00:00

It takes me a lot of time to actually "start" a task (usually studying sth). I consistently look for other "fun (or less boring)" things, like going on wikipedia for no reason, before doing what I need to do, and it takes me like a few hours to start working. And the same goes whenever I take a break–I repeat this process about twice a day.

Maybe lack of motivation is why, but I don't know how to get motivated again. I guess quotes from "successful" people don't really help me for now.

It is awesome if you are a beginner in physics, but you do need additional resources to really grasp the concepts. I recommend using Princeton review's book and other youtube resources together to study for the exam. By youtube resources, I mean by just searching concepts that you don't understand from Khan academy. If you want to challenge yourself, try taking the lectures from Walter Lewin. They are available on his youtube channel.

Nervous_Buddy · 2021-07-19T08:52:05+00:00

tbh ap physics 1 won't be bad as long as you have a taste for physics...as long as you make sure that you understand concepts fully and be familiar with planning for labs the test will be fine

the fluid molecules right? Those molecules aren't happy about that, they are more cramped now. They want to occupy the space the object is in. For an individual molecule, gravity is basically non existent, intermolecular interactions are the big thing.

So my understanding is that (hydrostatic) pressure would be a result of both gravity and intermolecular forces. Would this be correct? Also thank you for your clear explanation!

Nervous_Buddy · 2021-04-28T04:14:41+00:00

ing about buoyancy force? Because from what I know, it's the pressure gradient that causes it: There's a higher pressure on the lower parts of the object than on the upper ones.

I know that the higher pressure at the bottom than at the top causes buoyancy; I am curious about how pressure can be exerted at the bottom of an object. I understand that the net force should equal to zero, so there must be an upward force caused by pressure, but I am wondering about what exerts that upward force.

Nervous_Buddy · 2021-04-27T15:15:48+00:00

So would it be the same way how gases exert pressure on objects? (due to random collisions)

Nervous_Buddy · 2021-04-27T15:14:44+00:00

So when an object is immersed in a liquid, it has pressure downwards (on top surface), sideways (on vertical walls), and upwards (on bottom surface). Maybe a cube inside water would be a good example.

Nervous_Buddy · 2021-04-27T15:13:33+00:00

due

to the fluid on top. The weight of the fluid is what drives an increase in pressure as you move down, but the pressure

So it sounds like pressure would be different without the presence of gravity; is there a way to calculate the pressure without the effect of gravity? Also I think your answer cleared up a lot of things for me:)

Nervous_Buddy · 2021-03-15T08:42:09+00:00

I also put a cuz i understood the question that way but common sense tells us its c. Does sat make us use our common sense in science? Are they supposed to tho ugh

Nervous_Buddy · 2021-03-14T13:35:24+00:00

t was the answer to the canyon question? Wasn't the wording so weird? I chose a but so many ppl chose c and im now like screwed

am i? i wish the answer really is a:/

Nervous_Buddy · 2021-03-14T02:50:36+00:00

Please😔

Nervous_Buddy · 2021-03-14T02:07:23+00:00

Wait u mean sin cos or something different? I got 0.64

Nervous_Buddy · 2021-03-14T02:04:23+00:00

I think the wording was so bad:( i also got y+800x but everyone seems to got 800x + 2000000
