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.
For “Διάθλαση”, start from an observation or model, define quantities and units where relevant, and separate the changed factor from the measured outcome. Support the conclusion with data and state the test's limitations.
For “Ανάλυση λευκού φωτός”, start from an observation or model, define quantities and units where relevant, and separate the changed factor from the measured outcome. Support the conclusion with data and state the test's limitations.
For “Χρώματα”, start from an observation or model, define quantities and units where relevant, and separate the changed factor from the measured outcome. Support the conclusion with data and state the test's limitations.

In a safe test about “Διάθλαση”, the first condition gives 10 units and the second 7. Which is greater, and what should be kept the same?
The first value is greater by 3 units. A fair test changes only one factor.
Explain “Διάθλαση” in your own words and use a picture, objects, a table, or a simple measurement to support it.
A complete explanation connects the correct idea, a clear representation, and a sensible check.
Διάθλαση και χρώμα
Вісім завдань від базових навичок до екзаменаційного рівня. Спочатку виконайте самостійно.
Record 5 safe observations about “Διάθλαση” without writing a conclusion yet.
An observation is something seen, heard, or measured.
The response needs 5 specific observable or measurable statements, not guesses about cause.
Design a fair test for “Ανάλυση λευκού φωτός”: what changes, what is measured, and which 2 things stay the same?
Change one factor only.
Full response: one changed factor, one measurable outcome, and 2 controlled conditions.
Measurements are 4, 4, and 8 units. Put them in a table, find the greatest, and the difference from the least.
Use condition and measurement headings.
Greatest 8, least 4, difference 4 units.
Sort examples of “Διάθλαση” into two groups and state the sorting rule.
Each item should clearly match one group.
A full response gives two named groups, at least two examples in each, and an observable sorting rule.
Choose a suitable tool and unit to measure something connected with “Ανάλυση λευκού φωτός”.
Decide whether you measure length, time, mass, temperature, or volume.
The quantity, instrument, and unit must match, e.g. time-stopwatch-s or length-ruler-cm.
From data 6, 11, 16, predict the next value and explain the pattern.
Look for the constant change +5.
21; +5.
Write 2 safety rules for a simple activity about “Διάθλαση” and explain the risk each reduces.
Link each rule to a reason.
A full response gives 2 specific rules, each linked to a risk, and requires supervision where appropriate.
Data A=5 and B=9. Write a conclusion, evidence, and one limitation about “Ανάλυση λευκού φωτός”.
Do not claim more than the two values show.
B is 4 greater than A. The values support this, but two measurements alone do not prove a general rule.

Шість різних завдань від базового рівня до складного з часом, підказками та відповідями.
Homework 1: Record 8 safe observations about “Διάθλαση” without writing a conclusion yet.
An observation is something seen, heard, or measured.
The response needs 8 specific observable or measurable statements, not guesses about cause.
Homework 2: Design a fair test for “Ανάλυση λευκού φωτός”: what changes, what is measured, and which 3 things stay the same?
Change one factor only.
Full response: one changed factor, one measurable outcome, and 3 controlled conditions.
Homework 3: Measurements are 7, 5, and 12 units. Put them in a table, find the greatest, and the difference from the least.
Use condition and measurement headings.
Greatest 12, least 5, difference 7 units.
Homework 4: Sort examples of “Διάθλαση” into two groups and state the sorting rule.
Each item should clearly match one group.
A full response gives two named groups, at least two examples in each, and an observable sorting rule.
Homework 5: Choose a suitable tool and unit to measure something connected with “Ανάλυση λευκού φωτός”.
Decide whether you measure length, time, mass, temperature, or volume.
The quantity, instrument, and unit must match, e.g. time-stopwatch-s or length-ruler-cm.
Homework 6: From data 9, 15, 21, predict the next value and explain the pattern.
Look for the constant change +6.
27; +6.
