Question

Time taken by the sunlight to pass through a window of thickness 4 mm. Whose refractive index is 1.5 is
(a) (b) (c) (d)
@Physics

Answer 1

where are the options?

Answer 2

\[(a) 2*10^{-8} \sec\]
\[(b) 2*10^8 \sec\]
\[(c) 2*10^{-11} \sec\]
\[(d) 2*10^{11} \sec\]

Answer 3

well, the speed of light through the window will be the speed of light in space divided by 1.5
just divide .4 cm divided by that speed, u will get that answer :)

Answer 4

option c is correct
