Lenses and Images

When an object is placed on the focal point in front of a convex lens, the image produced is ___.

• real, reduced, and inverted
• real, enlarged, and inverted
• real, true, and inverted
• There is no image

When an object is placed between the focal point and the convex lens, the image produced is ___.

• real, reduced, and inverted
• real, enlarged, and inverted
• virtual, enlarged, and upright

• inverted and larger
• not inverted and smaller
• not inverted and larger

This image is...

Classify the image in the viewfinder lens of the camera.

• real

• virtual

• inverted

• upright

Classify the image formed in this scenario.

• real, inverted, larger than original

• real, inverted, smaller than original

• virtual, upright, larger than original

• virtual, upright, smaller than original
