From (1/f) = (μrel - 1)((1/R1)-(1/R2)) Focal length of lens will change hence image disappears from the screen

Image disappears

No change

Erect real image

Magnified image

$F ro m \frac{1}{f} = (μ_{re l} - 1) (\frac{1}{R _{1}} - \frac{1}{R _{2}})$
Focal length of lens will change hence image
disappears from the screen
