Question

Consider a converging mirror with radius of curvature equal to1.250m with an optical axis that goes left-right. An object of height30.00cm is placed to the left of the lens so the bottom of the object sits on the optical axis with do=1.910m.Place an X before all true statements regarding this mirror.

a) This mirror can only form inverted images.

b) For do<f, the image distance is negative.

c) If the object distance increases, the image is formed closer to the mirror.d

) No image is formed for do>R

e) If the object distance is equal to the mirror’s radius of curvature, the magnification is one.

f) The image gets smaller as d0 increases.

g) The mirror forms a virtual image forR>do>f

Answer 1

Some tips:

focal length of converging mirror is negative.

converging mirror always make upright, virtual image.

As the object distance is decreased, the image distance is decreased and the image size is increased.

_________________________________________________

This mirror can only form inverted images. - False

For do<f, the image distance is negative. - Image distance is always negative. True

If the object distance increases, the image is formed closer to the mirror - False

No image is formed for do>R - False

If the object distance is equal to the mirror’s radius of curvature, the magnification is one - False

The image gets smaller as d0 increases - True

The mirror forms a virtual image for R>do>f - It always forms a virtual image - True
