What reading level is Lectures Notes On Light book?
To quickly assess the difficulty of the text, read a short excerpt:
size of image Magnification = f, . " size of object 7*1 cms. ~~ 4-0 cms.
= 1-78. V _ 78*2 cms. U ~ 44'3 cms.
= 1-77.
. -. Magnification = -, 102 IN 77 REFRACTION OF LIGHT If a ray of light, travelling in any medium, comes in contact obliquely with another medium, part of it is reflected and part refracted.
In the diagram AB = incident ray.
EG = reflected ray.
ED = refracted ray. Z A BE = angle of incidence. Z DBF = angle of refraction.
Experiments to show the Refraction of Light 1. A parallel b...eam of light from a lantern was reflected by a mirror on to the sur- face of some coloured water in a trough.
The beam of light as it entered the water was bent towards the normal.
2. We arranged the trough so that a beam of light entered it at the side. It did not emerge, but was " totally reflected. " 3. A coin at the bottom of a trough full of water appeared to be raised. When the eye was placed on a level with the top of the water, the coin appeared to be almost on the surface.
4. A half-metre measure put in the water appeared to be bent.
