How to use it in a task
In a task about Rainbow, do not start from a random formula. First decide whether the question asks for a definition, calculation, unit, classification or interpretation. Then choose the rule: rainbow comes from refraction, reflection and dispersion.
| Step | Answer |
|---|---|
| Definition | Rainbow is treated as a practical school topic from Optics: definition first, then rule, example and answer check. |
| Formula or rule | rainbow comes from refraction, reflection and dispersion |
| Unit / notation | notation depends on the task wording |
| Why it matters | For Rainbow, check that the answer contains the definition, the correct notation (notation depends on the task wording) and an example matching the question. |
Expert example
sun position matters
For Rainbow, check that the answer contains the definition, the correct notation (notation depends on the task wording) and an example matching the question.
Solution procedure
- Decide whether Rainbow is given, required, or only needs to be defined.
- For Rainbow, write the notation and units first: notation depends on the task wording. This prevents a correct calculation from becoming a wrong answer.
- Apply the rule rainbow comes from refraction, reflection and dispersion before substituting numbers or choosing the example.
- Finish by checking the condition in the task: For Rainbow, check that the answer contains the definition, the correct notation (notation depends on the task wording) and an example matching the question.
How to interpret the result
A result for Rainbow is useful only when it answers the exact question. If the task asks for a calculation, give the number with the correct unit or symbol. If it asks for a definition, start with a precise sentence and use the formula only as support. A strong answer keeps those two levels separate.
The safest structure is to name the quantities, show the relation, and interpret the result. For Rainbow, that means connecting the definition, Rainbow is treated as a practical school topic from Optics: definition first, then rule, example and answer check., with the control point: For Rainbow, the common pitfall is using the right word without the condition from Optics..

Answer rubric
- The definition of Rainbow appears before calculation or example.
- The notation is correct: notation depends on the task wording.
- The example for Rainbow stays inside the Optics topic.
- The final check catches this error: For Rainbow, the common pitfall is using the right word without the condition from Optics.
