A glass of refraction index 1.5 and radius -.1 m has a small bubbl inside at a distance of 0.01 m from the centre. Where will the mark appear to the observer when viewed along the diameter containing the bubble?

Verified by Experts

`(n_(1))/(u ) + ( n_(2))/(v) = ( n_(1) -n_(2))/( R) ` or `( n)/( u ) + ( 1)/( v) = ( n +1)/( R )`
`(1.5) /(0.09) + ( 1)/( v) = ( 1.5-1)/( 0.1)`
`16.66 + ( 1)/( v) = 5`
`(1)/( v) = 5-16.66 = - 11.66 v = -0.0857m`
