Question

2.An object is placed 25.3 cm away from a spherical concave mirror. The radius of curvature of the mirror is 20.0 cm. Select the statement from the list above which best describes the image.

A real, upright and larger than the object B real, inverted and larger than the object C virtual, upright and smaller than the object D virtual, inverted and larger than the object E virtual, inverted and smaller than the object F real, inverted and smaller than the object G real, upright and smaller than the object H virtual, upright and larger than the object

Explanation / Answer

Number 1)

1/-10 = 1/25.3 + 1/q

q = -7.17 cm

M = -q/p

M = -(-7.17)/(25.3) = .283

Since q is negative and M is positive and less than 1, choice C is the answer

C virtual, upright and smaller than the object

Number 2

1/10 = 1/25.3 + 1/q

q = 16.5 cm

M = -(16.5)/25.3

M = -.652

Since q is positive and M is negative and less than 1, choice F is the answer

F real, inverted and smaller than the object
