The Nature of Light and the Laws of Geometric Optics EXAMPLES
90o 65o = 25o with the horizontal.
= 180o = 180o 2( )
= 180o 2[ (90o+ )]
= 360o 2
(A). Find the angle of refraction 2 = ?
Then: 2 = sin-1(n1 / n2) sin 1 = 19.2o
(B). Find the speed of the light once enters the glass.
From eqn. (35.4)
(C). What is the wavelength of this light in the glass?
From eqn. (35.7)
n1 = 1.33 and n2 = 1.00
