I need some help with the following question.
Thank You,

When an object is placed 8mm from a concave spherical mirror, a clear image can be projected on a screen 16 mm in front of the mirror. If the object has a height of 4 mm, the height of the image is?

I think it's 2 mm or 8 mm I am not certain.


2 mm
4 mm
8 mm
12 mm

  • Physical Science -

    The magnification ratio is
    D(image)/D(object) = 2

    If the object is 4mm high, the image height is twice that.

  • Physical Science -

    m=I/o = 16mm/8mm=2
