Question

03 AX- If you do not answer this question correctly in 3 attempts, you can get a hint. Suppose the figure above represents a ray of light going from air through crown class into water, such as going into a fish tank Calculate the amount the ray is displaced by the glass, dx, given that the incident angle is 42.1" and the glass is 1.10 cm thick. Crown glass has an index of refraction equal to 1.52.

Answer 1

Use Snell's law to find $\theta$₂

n₂sin$\theta$₂ = n₁sin$\theta$₁

1.52 * sin $\theta$₂ = 1 * sin 42.1

$\theta$₂ = 26.172 degree

x1 do not answer this question correctly in 3 attempts, you

so,

x1 = 1.10 * tan 26.172 = 0.5406 mm

x2 = 1.10 * tan 42.1 = 0.9939

so,

$\Delta$x = 0.4533 cm

$\Delta$x = 4.533 mm
