What reading level is A Third Year's Course in Practical Physics book?
To quickly assess the difficulty of the text, read a short excerpt:
Place the slab ob- liquely across the line PQ, touching the pin B (see diagram).
Look along AB through the slab, and place a pin C against the opposite surface of the slab so that A, B, and C (when seen through the slab) ap- pear to be in a straight line.
Place a fourth pin D beyond the slab so that A, B, and C, D (when seen through the slab) appear to be in a straight line.
Remove the slab. Join BC, CD. The original path of the light is along PQ. The new path is along ABCD. CD is called the Em...ergent Ray.
When the ray enters the slab at B it is turned from its first path. The angle (QBC) through which it is turned is called the Angle of Deviation.
70 PRACTICAL PHYSICS Measure the angle between the incident ray AB and the emergent ray CD. Are the two rays parallel?
The ray AB after its passage through the slab proceeds in the same direction as before, since CD is parallel to AB (but not in the same line as before). Does the slab cause a ray to deviate from its original direction ? What is the effect of the slab on the ray ?
