Answer 1

Answer:

Explanation:

Coz the measurements r on a scale

u= 50-12= 38

v= 88-50=38

==> R=38cm  {coz at 2f}

==>  (1) f=19cm

(2)

u = 50-31 =19

=f

(2) v = at infinity

(3)towards the lens = between p&f

==> v= on same side of object ; enlarged; VIRTUAL & ERECT

(4) Draw ray diagram of Between p& F
