Question

A glass slab (μ=1.5) of thickness 2 cm is placed on a spot. The shift of spot if it is viewed from top (A) (2/3) cm (B) (4/3) cm (C) (1/3) cm (D) (5/3) cm

Shift =t(1-(1/μ)) =2(1-(1/1.5)) =(2/3) cm

Q. A glass slab $(μ = 1.5)$ of thickness $2 c m$ is placed on a spot. The shift of spot if it is viewed from top

$\frac{2}{3} c m$

$\frac{4}{3} c m$

$\frac{1}{3} c m$

$\frac{5}{3} c m$

Shift $= t (1 - \frac{1}{μ})$
$= 2 (1 - \frac{1}{1.5})$
$= \frac{2}{3} c m$

32​cm

34​cm

31​cm

35​cm

Shift =t(1−μ1​) =2(1−1.51​) =32​cm
