## Learning Outcomes

The student learns the physical models, which are used to describe mechanical and electromagnetic oscillators. By combining individual oscillators, the student will be able to study both mechanical and emg wave motion. The course will give an understanding of the phenomena, which lead to the beginning of the era of quantum physics. The most important results of quantum physics, such as those related with the photon, the atom and the atomic nucleus will be studied in the course. The student will understand the energy band structure of crystalline solids, the difference between metals and semiconductors, as well as the most important technical applications of semiconducting materials. The student will learn the basic phenomena of quantum physics and the related technical devices. In addition to the theoretical understanding, the student will learn how to apply her knowledge experimentally in laboratory environment. The results are analysed, together with thorough error calculations with some experiments. Each student will write 2 reports on the measurements.

## Student's Workload

108 h, which contains 56 h of scheduled contact studies.

The assessment of student’s own learning 1 h is included in contact lessons.

## Prerequisites / Recommended Optional Courses

Electricity and Magnetism.

## Contents

Simple harmonic oscillations, damped oscillations, wave motion, electromagnetic oscillations and the associated wave motion, basics of quantum physics, the photon, Bohr ’s atomic model, applications of atomic physics, atomic nuclei.

## Recommended or Required Reading and Other Learning Resources/Tools

Pentti Inkinen, Reijo Manninen, Jukka Tuohi: "Momentti 2, Insinöörifysiikka", Otava.

## Mode of Delivery / Planned Learning Activities and Teaching Methods

The relevant theories of physics, together with associated problems and applications, are studied on a course of lectures. In addition, the student will individually solve a number of given homework exercises. Students will also take part in laboratory measurements. The measurements are done in groups of 3 students.

## Assessment Criteria

Grade 5: The student knows all the quantities and units discussed on the course, and she understands how they are related with each other. The student is able to independently apply the natural laws discussed on the course while solving complicated problems related with the contents of the course.

Grade 3: The student knows most of the quantities and units discussed on the course, and she understands a significant amount of the relationships between them. The student is able to apply the natural laws discussed on the course while solving medium-level problems related with the contents of the course.

Grade 1: The student knows the most important quantities and units discussed on the course, and she understand the most important relationships between them. The student is able to apply the natural laws discussed on the course while solving basic problems related with the contents of the course.

## Assessment Methods

The assessment is based on an examination, homework exercises and laboratory work. The student must solve at least 25 % of the given homework exercises, and she must complete all the associated experiments in the laboratory of physics, as well as write two reports on the measurements.
