A clear plastic sandwich bag filled with water acts as a converging lens in air. If the bag is filled with air and placed under water, is the effective lens converging or diverging?
diverging
An object is placed to the left of a converging lens. Which of the statements are true and which are false: The image is always to the right of the lens
false
An object is placed to the left of a converging lens, which of the following statements are true and which are false: The image can be upright or inverted
True
An object is placed to the left of a converging lens, which of the following statements are true and which are false: the image is always smaller or the same size as the object
false
When you see this card, open the chapter 23 concept questions and go over the image based problems
True or false? For an object at a concave mirror’s center of curvature, the image is real and inverted.
true
As an object approaches the focal point of a concave mirror, the image size shrinks to zero. True or false?
false
For an object in front of a convex mirror, the image is always virtual and upright
true
For an object in front of a diverging lens, the image is virtual and in front of the lens. True or false?
true
A converging lens always forms a real image and a diverging lens always forms a virtual image
false
For an object located at the focal point of any lens, the image magnification is equal to one. True or false?
false
Suppose you want to use a converging lens to project the image of two trees onto a screen. One tree is a distance x from the lens, and the other is a distance of 2x. You adjust the screen so that the near tree is in focus. If you now want the far tree to be in focus, do you move the screen towards or away from the lens?
towards the lens
Light from an object passes through a lens and forms a visible image on a screen. If the screen is removed, would you be able to see the image if you remained in your present position?
No
