3127Question 109 - (a) Acceptable wavefunction in quantum mechanics in the range of : negative infinity < x < positive infinity, vanishes at least at one boundary. Which of the following is the wavefunction or are the wavefunctions of acceptable theory : P = x, P = | x |, P = sin x, P = exp (-x), P = exp (-| x |)? State the reason. (b) Let linear momentum operator P = -ih d / dz. The wavefunction is S = exp (-ikz) where i x i = -1, k and h are constants. Find the linear momentum of such wavefunction by using the term P x S.

I have applied for a F1 VISA & I had appointments on 19th july and 2nd August but both times my VISA has been rejected due to unknown reasons I'm posting my conversation with VO both times 1st appointment 19 July Me: Good morning sir. VO: Hi. VO: Why do you want to go to IIT? Me: This institute provides one of the best courses in Mechanical Engineering. It has very good study atmosphere especially the faculty that is highly qualified. Most importantly It has very good student to faculty ratio ie. 10:1 that is highly favorable for student’s studies. VO: Which other universities have you applied to? Me: I have applied to Purdue, USC….( I was telling about other 2 universities also, but he interrupted) VO: Why not Purdue? Me: Coz I’ve got a rejection from there. VO: And what about USC? Me: I’ve got rejected there too. Also, I’ve applied to 2 other universities whose decisions are still awaited they are SUNY Buffallo and Texas A&M. VO: What are your qualifications? Me: I’ve done Civil Engineering from Jamia Millia Islamia University. VO: Can I see your marksheets please? Me: Sure ( I gave him my neatly clipped marksheet bundle..) VO: Do you have any backlogs? Me: No VO: Where are the marks? I’m just seeing the grades.. Me: They just provide us with these grades and there is a CPI at the end. (I was thinking I got my VISA but he returned all my forms back along with some US embassy brochure and replied…) VO: Thank you..you don’t qualify for the US VISA this time. ( I maintained my composure and asked..) Me: Can you tell me the reason please? VO: Read the brochure. ( I was feeling devastated but I smiled back and said..) Me: Thank you. 2nd appointment 2 August Me: Hello sir, How r u.. VO: Fine, Where r u going? Me: Illinois Institute of Technology VO: Why IIT? Me: The courses required for MS in mechanical Engineering at IIT are very much related to what have i done in my undergrads, there are subjects like thermodynamics, engineering mechanics, fluid mechanics, mechanics of materials that i've already studied, so definitely it will be a plus point and also its faculty is very good and student to faculty ratio is 10:1 that is highly favorable. VO: R u working somewhere? Me: Yes, I'm working in Vimtech infrastructure pvt ltd as a technical supervisor. VO: What is your percentage? Me: Sir we have a grading system in our university and different weightage is assigned to each grade and weighted mean is calculated that is called as CPI ie cumulative percentage index and i've a cpi 6.3/10. VO: That is a quite low. Me: No sir, there is a formula given at the back of marksheet which calculates my %age as 64.2 VO: Show me your marksheets. Me: Sure VO: Do u have any backlogs? Me: No, Sir VO: You have a lot of C grades.(He returned my documents back and said) VO: You need to prove that u r a credible student. GRE: 1330( Q770;V560) TOEFL 96 University: Illinois Institute Of Technology There's one more thing that i need to tell u that i have got around 16 backlogs in my undergrads, but i've cleared them all and they are not reflected in my marksheets but the year mentioned in my marksheets is of when i clear all papers of a particular semester. Can it be a problem? What should i do now ? should i reapply for a US VISA as my joining date as per my I20 is 23 August. Kindly suggest me something
