Aaltoliikettä
Aaltoliike, meaning wave motion in Finnish, refers to the propagation of disturbances from one place to another. This phenomenon is fundamental to many areas of physics, describing how energy is transferred without a net transfer of matter. Waves can be broadly categorized into mechanical waves and electromagnetic waves.
Mechanical waves require a medium to travel through, such as solids, liquids, or gases. Examples include sound
Electromagnetic waves, on the other hand, do not require a medium and can propagate through a vacuum,
Key properties of wave motion include wavelength, which is the spatial period of the wave; frequency, the
