If an image is said to have a magnification of -2, which of the following are true?(choose all that apply) A. The object is larger than the image B. The image is larger than the object C. The image is inverted D. The image is upright

When created by a single optic    A. Both real and virtual images are upright.   B. Real images are upright and virtual images are inverted.   C. Real images are inverted and virtual images are upright.   D. Both real and virtual images  are inverted.

A thin lens has a focal length of 25.0 cm. A. Locate the image when the object is placed 26.5 cm in front of the lens. State if the image is real or virtual, enlarged or reduced, and inverted or upright. B. Locate the image when an object is placed 23.0 cm in front of the lens. State if the image is real or virtual, enlarged or reduced, and inverted or upright.

what is the correct answer?  a ray passing through an object focal point of an optical system will: A) Pass through the image focal point B) Pass through the image nodal point  C) not change the direction  D) become parallel to the optical axis  E) take a direction that depends on the position of the principle point

If the image from a lens has a magnification of -0.5 what does that mean?   A. image is inverted, smaller than object B. image is inverted larger than object C. image is upright, smaller than object D. image is upright, larger than object

An object lies outside the focal point of a concave mirror. Which of the following statements about the image formed by this mirror is the most accurate?   A. The image is always virtual and upright.   B. The image could be real or virtual, depending on how far the object is past the focal point.   C. The image could be upright or inverted, depending on how far the object is past the focal point.   D. The image is always on the opposite side to the object.   E. The image is always real and inverted.

An object is 15 cm away from a mirror. The mirror has focal length of 30 cm. The image distance is calculated to be?    A. - 30 cm   B. 30  cm   C. - 0.03 cm   D. 0.03 cm

An object is placed 4cm left of a converging lens with a focal length of 10cm. a. Make a sketch of this arrangement and draw 3 principal rays to find where the image should form.   b. Is the image real or virtual? c. Use the thin lens equation to calculate the position of the image. d. (New situation) An object is placed 30 cm to the left of a diverging lens of focal length 20 cm. Sketch this arrangement by drawing 3 principal rays. Draw where you think the image should form
