T3 (Wednesday 10:30-14:00)

Semester requirements:

• Everyone should perform 7 laboratory experiments, based on the weekly schedule above.
• Students must arrive prepared and on time for the practice.

Laboratory report (50% of the final grade):

• A written laboratory report about each of the practices performed should be submitted to the instructors (Dr. Katalin Ősz or Ildikó Rapp-Kindner)
• Everyone must submit their own report individually, even if the measurements were performed in 2- (or 3-)membered working groups.
• Laboratory reports should be prepared on paper. You can use either plain A4 paper or graph paper.
  • The first page must include the following information: name, date, practice title, group name (T1, T2 or T3).
  • Theory Section: A one-page theory section is mandatory and must be brought to the practice. Failure to provide it may result in the student being sent away.
  • Practice Description: A one-page description of the practice is also required. Failure to provide it may result in the student being sent away.
  • Measurement data, calculation results, details of the calculations, graphs (on graph paper, or printed from Excel or other fitting program) should also be submitted.
  • Finally, summarize the results in a few sentences and draw your conclusions.

• The use of a red pen for preparing the lab report is prohibited.

• Submission: The laboratory report must be submitted during the practice in the following week.
  • Last submission deadline: 10 December 2025.
• Laboratory report return: Corrected laboratory reports will be returned at the earliest in the week following submission.
  • Last return date: 17 December 2025.

Grading

The final grade is 50-50% based on the laboratory practice reports and the written exam.

Written exam (50% of the final grade):

• Dates are announced in NEPTUN. You must register in NEPTUN for the selected date.
• Types of question on the written exam:
  1. multiple choice questions (based on the lecture material),
  2. short essays, basic equations, definitions, and diagrams (based on the lecture material),
  3. false or true questions (based on the lecture material),
  4. calculations (based on the laboratory practice).

• A SAMPLE TEST can be downloaded here.
