Need Asap please An object is located in air $47$ cm from the vertex of a concave surface made of glass with a radius of curvature $16$ cm$.$ Where does the image by refraction form? Use

nair $=1$

and

nglass $=1\mathrm{.}5.$

$($Give the image distance in centimeters.$)$An object is located in air $47cm$ from the vertex of a concave surface made of glass with a radius of curvature $16cm.$

What is its magnification?
