Course description:
Theory of oscillations: harmonic oscillation,
composition and decomposition of oscillations; damped and forced oscillations,
coupled oscillations. Concept of waves, the wave equation. Phase and group
velocity. Reflection, refraction, interference and diffraction of mechanical
waves. Dispersion. Sound waves: oscillations of strings, sticks, disks
and columns of air. Characteristics of the sound field, features of sound
propagation. Hearing, the structure of the ear. Concepts concerning hearing,
damage of hearing. Ultrasonic sounds. Basic concepts of the theory of light,
measuring the velocity of light. Laws of refraction and reflection. Index
of refraction. Total reflection and its application in prisms and optical
fibres. The Fermat principle and its application. The concept of the optical
picture. Optical image production with spherical mirrors and via spherical
and plane surface refraction. Thin and thick lenses, most common errors
in image production. The eye and sight, correction of the optical errors
of the eye. Important optical devices: photo-cameras, projectors, microscopes
and telescopes. The phenomenon of dispersion, dispersion prisms. The concept
of the spectrum, the prism-spectroscope. Interference, temporal and spatial
coherence. Light diffraction. Fresnel- and Fraunhofer-type diffraction..
Optical gratings. Holography. Polarisation, double refraction and polarisation
in crystals.
