Question

Light travels from air into an optical fiber with an index of refraction of 1.44.  (a)  In which direction does the light bend?  (b)  If the angle of incidence on the end of the fiber is 22o, what is the angle of refraction inside the fiber?  (c)  Sketch the path of light as it changes media.

Answer 1

@) FROM RARER TO DENSER MEDIUM IT BENDS TOWARDS THE NORMAL..

ß)

$\sin(i) \div \sin(r) = 1.44$

c)in drawing
