You possibly can reply this query very simply if you happen to keep in mind the next equation: 1/f = 1/i 1/o.
f is the focal size
i is the gap of the picture from the mirror
o is the gap of the article from the mirror.
so 1/9.50 = 1/i 1/29
1/i = 1/9.50 1/29
1/i = 29/275.5 9.5/275.5 (needed to discover widespread denominator)
1/i = 19.5/275.5
i = 275.5/19.5
i = 14 cm
so 1/9.50 = 1/i 1/29
1/i = 1/9.50 1/29
1/i = 29/275.5 9.5/275.5 (needed to discover widespread denominator)
1/i = 19.5/275.5
i = 275.5/19.5
i = 14 cm
