1.) An object's image formed by a thin positive lens will be bigger if the image is
a.) Closer to the lens than the object
b.) farther from the lens than the object
c.) neither matters
2.) When you see an object:
a.) a real image is formed on your retina
b.) a virtual image is formed on your retina
c.) a virtual image is formed on your cornea
Que1
Option a is correct
closer to the lens than object
Que 2
Option b is correct
A virtual image is formed on retina

An object is placed to the right of a converging lens and an image is formed to the left of the lens. lens object image 1) Following the standard sign convention for the lens equation 5 + 5 = }, the image distance is: positive negative Submit 2) The image is: real virtual Submit 3) For this lens, the sign of the focal length is: positive negative Submit Help 4) An object is placed to the left of a converging...
Starting from very far away, an object is moved closer and closer to a diverging lens, eventually reaching the lens. What happens to its image formed by that lens? A) The image always remains real. B) The image stays in the same position. C) The image gets farther and farther from the lens. D) The image eventually changes from real to virtual. E) The image keeps getting larger and larger.
Thin lenses lab. Plz answer How does the size of the image change when you move the object from focal point (do-f) towards the converging lens (do - 0)? Your Answer: Is this a real image or virtual? V For a convex lens when are they formed ? Your Answer: How does the size of the image change when you move the object from the focal point (do=f) towards the diverging lens (do -70)? Your Answer: Is this a real...
Dealing with a lens and a real object, a positive magnification factor of the lens means that O O O O O the image will be taller than the object. that lens must be of the converging type. the object is farther from the lens than the image. the object distance will turn out to be positive. the image formed by the lens will be upright.
An object is placed 10.6 cm in front of the cornea. (The cornea is thin ans has approximately parallel sides so that the reflection that occurs as light travels from air to cornea to aqueous humor is essentially the same as though the aqueous humor were directly in contact with the air. The aqueous humor has index of refraction n = 1.34 and the radius of curvature of cornea is 7.8 mm.) (a) What is the image distance for the...
