8. What is the angle of deviation if a ray of light in water is incident at an angle of 50 degrees and the angle of refraction is 35 degrees? Draw & compute.
Transcribed Image Text:Example Case Problem
A light ray travels from air to crown glass. If the
angle of incidence is 20 degrees, what is the
angle of refraction?
n sin 0=n sin ở
1.00 sin 20° = 1.52 sin ở
1.00(0.34202)=1.52 sin ở
0.34202=1.52 sin 0

ANGLE OF DEVIATION
Angle of deviation is the angle produced after the Angle of Refraction.
Formula:
Ld -L-Lr
*if the angle of refraction is more than the angle of incidence then:
Ld-Lr-LI
Ld (TIR) - 180-2 u
