NCERT Class 12 Physics Physics Part II Full Book Test Mock Test
This full-book test draws 25 questions from every one of the 6 chapters in the NCERT Class 12 Physics Part II textbook, in chapter order. Chapter tests tell you whether you remember a chapter you have just read; this one tells you what survives once the whole book is behind you, which is the harder and more useful question. Every item is set from the book text and carries a full explanation, so a wrong answer points you back to the exact chapter to revise. Use it as a revision check before school exams, or as a base-building drill if you are preparing for UPSC, SSC or a state PCS, where NCERT is the standard starting text. No negative marking.

Sample Questions
Q1.An optical fibre transmits a light signal along its length because:
- AThe cladding has a higher refractive index than the core, so the light is refracted inwards at each boundary
- BThe fibre is coated with a reflecting metal film on its outer surface
- CThe core has a higher refractive index than the cladding, so the light is totally internally reflected repeatedly at the core-cladding boundary
- DThe light is absorbed and re-emitted along the axis at each stage
Q2.The lens maker's formula shows that for a double concave lens made of glass in air:
- AR1 is negative and R2 positive, so the focal length comes out negative
- BR1 is positive and R2 negative, so the focal length comes out positive
- CThe focal length is independent of the refractive index of the glass
- DBoth radii are positive, so the focal length is always positive
Q3.The chapter warns that optical density must not be confused with mass density, and gives as an example the pair:
- ATurpentine and water, turpentine having the higher mass density but the lower optical density
- BDiamond and glass, diamond having the lower mass density
- CTurpentine and water, turpentine having the lower mass density but the higher optical density
- DAir and vacuum, air having the lower optical density
