Optical fibres use the phenomena of Total internal reflaction
The power of a lens of focal length – 25 cm is 4 dioptrel
As a ray of light falls normally on a glass slab. the refracting angle is Zero
Light bends on traveling into a different media as its Speed differs.
Magnification is always The product of the magnification of the combining lenses.
