## Changes in the course due to coronavirus

Autumn 2020 and Spring 2021 the exams of most courses at the MN Faculty will be conducted as digital home exams or oral exams, using the normal grading scale. The semester page for your course will be updated with any changes in the form of examination.

Please note that there may be changes in the form of examination for some courses taught Spring 2021. We aim to bring both the course description and the semester page of all courses up to date with correct information by 1 February 2021.

## Course content

The course offers an introduction into mechanical and electrical oscillations and a description of related phenomena like resonance. It introduces mechanical and electromagnetic waves, and explores different wave phenomena like phase and group velocity, standing and propagating waves, coherence, diffraction and interference, reflection, refraction, dispersion, and simple geometric optics. The course also includes an introduction into oscillation and wave analysis using Fourier and Wavelet transformations.

## Learning outcome

After completing this course you should:

• be able to recognize and use a mathematical oscillator equation and wave equation, and derive these equations for certain systems, point out the limitations and be able to refer to very different solutions of identical oscillator equations due to different initial and boundary conditions.
• explain how several waves or parts of waves interact, and be able to calculate and analyse diffraction and interference phenomena, and explain the conditions required for such phenomena to appear.
• describe and calculate what happens when waves move from one medium to another, and be able to explain dispersion and group and phase velocity.
• use geometric optics to describe and explain optical instruments, and by simple measurements estimate what strength glasses a person needs.
• explain several phenomena we can observe in everyday life that can be explained as wave phenomena, and identify basic principles, such as the Fresnel principle, to explain various phenomena.
• use both analytical mathematics and numerical methods to explore the subjects mentioned above. In particular you should be able to analyse experimental oscillator or wave phenomena, such as sound, using suitable methods.
• gather relevant information by yourself, and seek help from others to solve an extensive assignment where all necessary information is not supplied.
• write a thorough project report describing the topic, the methods used, results and conclusions clearly.

Students who are admitted to study programmes at UiO must each semester register which courses and exams they wish to sign up for in Studentweb.

In addition to fulfilling the Higher Education Entrance Qualification, applicants have to meet the following special admission requirements:

• Mathematics R1 (or Mathematics S1 and S2) + R2

And in addition one of these:

• Physics (1+2)
• Chemistry (1+2)
• Biology (1+2)
• Information technology (1+2)
• Geosciences (1+2)
• Technology and theories of research (1+2)

The special admission requirements may also be covered by equivalent studies from Norwegian upper secondary school or by other equivalent studies (in Norwegian).

## Overlapping courses

• 3 credits overlap with FYS111.

## Teaching

The first lecture is mandatory. If you are unable to attend, the Department has to be informed in advance (e-mail studieinfo@fys.uio.no), or else you will lose your place in the course.

The course extends over a full semester with 9 hours of teaching per week:

• 3 hours of lectures
• 2 hours of group sessions
• 4 hours of problem-solving which includes help with the computational essay

The course comprises the following obligatory activities:

• 6 compulsory assignments
• Computational essay

Participation in group sessions throughout the semester (at least 70%) can replace one compulsory assignment. 5 of 6 assignments (4 of 6 by the participation on at least 70% of group sessions) and the computational essay must be approved before you can sit the final exam.

## Examination

• A 4 hour final written exam, which counts 100% towards the final grade.

This course has mandatory exercises that must be approved before you can sit the finale exam.

### Examination support material

• Approved calculator
• Rottman: "Matematisk formelsamling"
• Øgrim and Lian or Angell and Lian: "Fysiske størrelser og enheter"
• One page with formulas (will be handed out together with the exam papers)

### Language of examination

The examination text is given in Norwegian. You may submit your response in Norwegian, Swedish, Danish or English

### Resit an examination

This course offers both postponed and resit of examination. Read more:
