sir,can you please tell me important questions that may appear from light,reflection and refraction and human eye and the colourful world ?(phycics cbse)
We cannot exactly give you the important questions which,might appear in the paper.
However, following are the most important topics which has to be studied:
Light – Reflection and Refraction
- Laws of reflection and refraction
- Terms and sign conventions related to spherical mirror and lenses (derivation is not required)
- Rules for tracing images formed by spherical mirrors and lenses
- Numerical problems based on mirror formula and lens formula, power of lens, practical based questions.
- Ray diagrams for image formation by spherical mirror and lenses.
The Human Eye and the Colourful World
- Defects of vision and their correction
- Refraction of light through a prism
- Dispersion and scattering of light and their application in daily life
- Numerical problems based on nature of lens and power required to correct eye defect.
