Your institute runs either Cyber Sensitization and Digital Hygiene (ICT-112, 4 credits) or Engineering Physics-II with its laboratory (ICT-114T and ICT-114P) — only one of the two is offered.
74 practice questions for Engineering Physics-II (ICT-114T), arranged the way the paper is set: short-answer questions for the compulsory Question 1, then twelve-mark questions unit by unit. Compiled from the official GGSIPU 2026-27 syllabus. Answers are not included — the unit-wise notes for this paper are where they are worked out. This is not a previous year paper.
Complete unit-wise notes for ICT-114T, written against the GGSIPU 2026-30 first-year syllabus. Unit I: Oscillations and Waves. Unit II: Ray Optics and Optical Instruments. Unit III: Interference and Diffraction. Unit IV: Lasers and their Applications. Each unit opens with the syllabus text as the scheme prints it, and closes with the questions this unit is actually asked. 129 pages.

IPU end-semester examination, June 2026, sat under the previous scheme as BS106 Applied Physics 2. The 2026 scheme has not been examined yet, so this is the nearest real paper for this subject.
IPU end-semester examination, June 2025, sat under the previous scheme as BS106 Applied Physics 2. The 2026 scheme has not been examined yet, so this is the nearest real paper for this subject.

Full worked solutions to the June 2026 End Term paper for Applied physics – II (BS106), GGSIPU first semester B.Tech. All 25 questions and parts the paper set are answered, including both alternatives wherever the paper offered a choice, so nothing depends on which questions you would have attempted. Derivations are written out in full and every numerical carries its working and its units. The questions are reproduced from the paper, so this document stands on its own; it is the answers to that paper, not the paper itself, which is listed separately. This paper was sat under the previous scheme, whose Applied physics – II (BS106) the subject on this page replaced; the paper itself is listed on this page for the same reason.
Official GGSIPU syllabus for the B.Tech 2026-30 batch (first year, under USICT), applicable from the academic session 2026-27.
