transparent photographic slide is placed in front of a converginglens with a focal length of 2.60 cm.The lens forms an image of the slide 13.5 cm from the slide.

(a) How far is the lens from the slide if theimage is real? (Enter 'none' in the second box if there is only oneanswer.)

(b) How far is the lens from the slide if the image is virtual?(Enter 'none' in the second box if there is only one answer.)

nearer possible distance = | cm |

further possible distance = | cm |

(b) How far is the lens from the slide if the image is virtual?(Enter 'none' in the second box if there is only one answer.)

nearer possible distance = | cm |

further possible distance = | cm |

nearer possible distance = correct check mark cm

further possible distance = correct check mark cm

(b) How far is the lens from the slide if the image is virtual?(Enter 'none' in the second box if there is only one answer.)

nearer possible distance = wrong check mark cm

further possible distance = correct check mark cm
