Oscillation that transfers energy
A wave transfers energy and information without net transfer of matter. Distinguish amplitude, wavelength, period, and frequency.

Ταλαντώσεις: structured theory, worked examples, answered practice, and a mastery checklist for Greek Lyceum Grade 3.
Unit
The essential chapter ideas in a clear sequence before practice.
A wave transfers energy and information without net transfer of matter. Distinguish amplitude, wavelength, period, and frequency.
The relation v = fλ connects the medium and the oscillation. At a boundary, source frequency stays fixed while speed and wavelength may change.
Use the normal, angles, and wavefronts. Superposition adds displacements without permanently changing the component waves.
Physics
Follow the method step by step and check why every step is valid.
A wave has frequency 4 Hz and wavelength 2.5 m. Find its speed.
Physics
Panhellenic physics requires diagrams, principle selection, equations, units, time management, and chapter connections.
The structure follows the official textbook layout and is used to organise study.
The areas that usually create mistakes or need extra revision.
v = 10 m/s
Before calculating, explain the key idea from “Απλή αρμονική ταλάντωση” and which conditions must be checked.
The answer should show not only which rule is used for “Απλή αρμονική ταλάντωση”, but also why it is valid here.

Try independently, use the hint if needed, then open the answer guide.
1. Explain the idea and give one correct foundation example for “Απλή αρμονική ταλάντωση”.
Write known quantities in SI units, draw a diagram where useful, and state the law before substitution.
A complete answer links “Απλή αρμονική ταλάντωση” to a physical law or model, correct units, and an interpretation.
2. Solve an application and show every intermediate step for “Ενέργεια ταλάντωσης”.
Write known quantities in SI units, draw a diagram where useful, and state the law before substitution.
A complete answer links “Ενέργεια ταλάντωσης” to a physical law or model, correct units, and an interpretation.
3. Compare a correct and an incorrect approach and justify the difference for “Ηλεκτρική ταλάντωση”.
Write known quantities in SI units, draw a diagram where useful, and state the law before substitution.
A complete answer links “Ηλεκτρική ταλάντωση” to a physical law or model, correct units, and an interpretation.
4. Create a short exam-style question and check your answer for “Φθίνουσες και εξαναγκασμένες ταλαντώσεις όπου προβλέπονται”.
Write known quantities in SI units, draw a diagram where useful, and state the law before substitution.
A complete answer links “Φθίνουσες και εξαναγκασμένες ταλαντώσεις όπου προβλέπονται” to a physical law or model, correct units, and an interpretation.
