Are these sentences same?

 

[emsr2d2]

1. Whom did you laugh at?
2. At whom did you laugh?

In the first, "at" stands at the end of the sentence and in the second,"at" is with the [STRIKE]preposition[/STRIKE] ​pronoun.
[STRIKE]Are[/STRIKE] Do these sentences mean the same?

Yes, they mean the same.

In case my marks aren't clear, you need to put a space after the full stop after the numbers 1 and 2.

Don't ask "Are these sentences the same?" They are clearly not the same (that means identical) because the words are in a different order.

"Who did you laugh at?" Does this sentence means the same?
Here "who" is in objective case right?
and could you please tell me passive voice of "Who did you laugh at?"

 

[Roman55]

'Who did you laugh at' is the way most native speakers would say it. That sentence in the passive voice would not be at all natural.

"Who was laughed at by you?" is passive voice of "Whom did you laugh at?" Am I right?

 

[Matthew Wai]

You are right, but it is not right to use the unnatural passive form.

"Who was laughed at by you?" is passive voice of "Whom did you laugh at?" then, can we write the passive voice " At who was laughed by you?" and I think it is not the unnatural passive form because I found this is in https://www.englishpractice.com/grammar/changing-interrogative-sentence-passive/

Finally, here is my doubt. Can we write prepostions at the end of the sentence and with the ​pronoun in both Active voice and Passive voice?

I think it is intended to show you how to change a sentence into the passive rather than how to write a natural sentence.

"Who was laughed at by you?" is passive voice of "Whom did you laugh at?" then, can we write the passive voice " At who was laughed by you?" and I think it is not the unnatural passive form....

The second is ungrammatical and unnatural. The first is merely unnatural. No native speaker would ever express this question in the passive voice.

 

[Tdol]

can we write the passive voice " At who was laughed by you?"

No, you can't.
