I look at my image in a round Christmas ornament. Which of the following will be true?

How far from a converging mirror should I put an object if the mirror has a radius of curvature of 1 meter and I want the image to be the same size as the object? A : less than 0.25 m B : 0.25 m to 0.75 m C : 0.75 m to 1.25 m D : 1.25 m to 3 m E : more than 3 m.

  1. How far from a converging mirror should I put an object if the mirror has a radius of curvature of 1 meter and I want the image to be the same size as the object? A : less than 0.25 m B : 0.25 m to 0.75 m C : 0.75 m to 1.25 m D : 1.25 m to 3 m E : more than 3 m

  2. I look at my image in a round Christmas ornament. Which of the following will be true? A : The image will be upright (not inverted) and real. B : The image will be upright and virtual. C : The image will be inverted and real. D : The image will be inverted and virtual. E : The ornament will shatter.

  10. Group question: Which of the following describes the image for a thin converging lens that forms whenever the magnitude of the object distance is less than that of the lens' focal length? • Real and upright • Real and inverted • Virtual and upright • Virtual and inverted

  11. ETHICS VS. MORALS • What is the difference between being polite and being kind?

  12. Playing with optics . . .

  13. Discussion Question: A lens is used to image an object onto a screen. If the right half of the object is covered, • The left half of the image disappears. • The right half of the image disappears. • The entire image disappears. • The image becomes blurred. • The image becomes fainter.

  14. Group question: Which of the following describes the image for a thin diverging lens that forms whenever the magnitude of the object distance is less than that of the lens' focal length? • Real and upright • Real and inverted • Virtual and upright • Virtual and inverted

  15. When can a diverging lens make a real image?

  16. Assuming the two lenses are made of the same material, which will have a larger f? A B C – they are the same

  17. If the lens had a lower index of refraction, the image be A.Larger, further away B.Smaller, further away C.Larger, closer D.Smaller, closer E. No change
