Explanation / Answer

here,

the object distance , do = 62 cm

the object height , ho = 1.3 cm

focal length , f = 19 cm

a)

let the image distance be di

using the lens formula

1/f = 1/di + 1/do

1/19 = 1/di + 1/62

solving for di

di = 27.3 cm

b)

the height of flame's image , hi = ho * ( - di/do)

hi = 1.3 * ( - 27.3 /62) cm

hi = - 0.57 cm
