A transparent cube of 0.21 m edge contains a small air bubble. Its apparent distance when viewed through one face of the cube is ${\rm{0}}{\rm{.10 m}}$ and when viewed from the opposite face is ${\rm{0}}{\rm{.04 m}}$. The actual distance of the bubble from the second face of the cube is

${\rm{0}}.{\rm{06}}\,\,{\rm{m}}$

${\rm{0}}.{\rm{17}}\,\,{\rm{m}}$

${\rm{0}}.{\rm{05}}\,\,{\rm{m}}$

${\rm{0}}.{\rm{04}}\,\,{\rm{m}}$

A transparent cube of 0.21 m edge contains a small air bubble. Its apparent distance when viewed through one face of the cube is

\mathrm{0}\mathrm{.10 m}

and when viewed from the opposite face is

\mathrm{0}\mathrm{.04 m}

. The actual distance of the bubble from the second face of the cube is

View answer and explanation

Correct option: A

\mathrm{0}.\mathrm{06}\,\,\mathrm{m}

Option A (

\mathrm{0}.\mathrm{06}\,\mathrm{m}

) is correct because it is calculated using the formula for apparent depth and the given distances.
