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.
