Find the apparednt distance between the ...

Find the apparednt distance between the observer and the object shwon in the figure and shift in the position of object.

Text Solution

Verified by Experts

The correct Answer is:
`35cm, "Shift" = 5 cm`
Apparent shift `= t(1 - (1)/(mu)) = 10(1 - (1)/(2)) = 5cm` towards slab.
Apparent distance `= 10 + 20 + 20 - 5 = 35cm`

An observer looks at an object kept at a distance 30 cm in air. If a rectangular glass plate ( mu =1.5) is placed between the observer and the object with its thick-ness along the line of observation, the object appears to the observer to be at a distance 25 cm. Find the thickness of glass plate. Position of the glass plate is now shifted (i) from object towards observers (ii) from observer towards the object How does it change the apparent position of the object as seen by the observer?
