Question

Pick out the WRONG statement from the following :

• A. Lateral shift increases as the angle of incidence increases.
• B. Lateral shift increases as the value of refractive index increases.
• C. Normal shift decreases as the value of refractive index increases.
• D. Both normal shift and lateral shift are directly proportional to the thickness of the medium

Answer 1

Answer: (B)

Lateral shift $L _{ s }$; $L _{ s }= t \frac{\sin ( i - r )}{\cos r }$
Normal shift $L _{ n }$
$L _{ n }= t \left[ 1 -\frac{1}{\mu}\right]$
$L _{ n }= t \left[ 1 -\frac{1}{\mu}\right]$
$\mu$ refractive index. From the equations option $A , C , D$ are correct. And $B$ is the wrong statement.
