Consider a rectangular slab, whose refractive index varies as 
, where 
.
Match the Column I with Column II.
Column I | Column II | ||
(A) | The equivalent refractive index of slab for normal incidence. | (I) | |
(B) | The apparent depth of point (in m). | (II) | 0.693 |
(C) | The optical path of a ray along (in m). | (III) | 1.5 |
(D) | The time (in second) taken by light ray to go vertically from point to point. | (IV) | 1.44 |
Choose the correct answer from the options given below.
Text Solution
Verified by ExpertsThe correct answer is:
C
Apparent depth 
( 
)
Optical path 
Time 
Hence, A-(IV), B-(II), C-(III), D-(I).
