#### Learning Outcome

After successful completion of the module the students got an overview of the basics of electricity and optics and are thus able to solve simple problems in these fields of physics by themselves. Furthermore the students got an overview of the basic concepts of modern physics - this includes knowing the basic technical terms and remembering basic relations.

#### Learning and Teaching Methods

Lecture: ex-cathedra teaching with demonstration experiments

Exercise to Physics II for Geodesy and Geo-Information: students get problem sheets and try to solve these problems by themselves before coming to the tutorial. During the tutorial sample solutions are presented by students or the lecturer and also possible alternative ways to solve to the problems are discussed. Students who present at least two solutions per term during the tutorial and who work through the problem sheets regularly (i.e. they miss at most two problem sheets) can get a bonus of 0.3 on the grade of the module. Following these tutorials will help the students to be prepared to solve the problems during the written exam.

#### Media

During the lecture a powerpoint presentation is used and some contents are explained using the blackboard. Additionally some example videos are shown during the lecture. For the exercises problem sheets are provided. Also an e-learning course is offered via Moodle. Presentation slides and problem sheets as well as sample solutions to problems which have already been discussed in the tutorials are available on this platform.

### Module Exam

#### Description of exams and course work

There will be a written exam of 60 minutes duration. Therein the achievement of the competencies given in section learning outcome is tested exemplarily at least to the given cognition level using calculation problems and comprehension questions.

For example an assignment in the exam might be: The exam is held in German: Zwei Kondensatoren C1 und C1 haben die selbe Fläche von A=30 cm2 und den selben Plattenabstand von d=8 mm. In C1 befindet sich kein Dielektrikum, C2 ist vollständig mit einem Dielektrikum mit relativer Dielektrizität 3 gefüllt. Zeichnen Sie jeweils den Schaltplan und berechnen die Gesamtkapazität (epsilon0 = 8,854e-12 F/m) a) wenn beide Kondensatoren parallel geschaltet sind. b) wenn beide Kondensatoren in Serie geschaltet sind.

In the exam the following learning aids are permitted: pocket calculator

Participation in the tutorials is strongly recommended since the exercises prepare for the problems of the exam and rehearse the specific competencies.

There will be a bonus (one intermediate stepping of "0,3" to the better grade) on passed module exams (4,3 is not upgraded to 4,0). The bonus is applicable to the exam period directly following the lecture period (not to the exam repetition) and subject to the condition that the student passes the mid-term of

- working through the problem sheets regularly (missing most two problem sheets)
- presenting at least two sample solutions to the problems to the group

#### Exam Repetition

There is a possibility to take the exam in the following semester.

#### Current exam dates

Currently TUMonline lists the following exam dates. In addition to the general information above please refer to the current information given during the course.
