Virtual image is an optical image formed from the apparent divergence of light rays from a point, as opposed to an image formed from their actual divergence.
So here only the movie at a theatre is actually diverging,all other are apparent divergence.
Select the one of the following that is NOT a virtual image Image seen in a...
1) Which of the following produces a magnetic field? a stationary net charge b electric current c mass d heat 2) A long copper wire of radius 10cm is laid on the ocean floor connecting an island to the mainland. A small species of shrimp is sensitive to magnetic fields, and it will die if subjected to a field strength greater than 0.004T. What current run through the cable would produce a magnetic field of this strength at its surface?...
1. What is another example of a "real image" besides a movie theater and the humans eyes? 2. What is another example of a "virtual image" besides a mirror?
4. What are the conditions necessary to form a virtual image using a converging lens? 5. What type of lens is used in a magnifying glass? Explain how to use the magnifying glass properly to see the largest possible image. Where should your eye be located and where should the object be located?
A magnifying glass is used for reading a book with a very small print. Select a correct answer (more than one can apply). A) The book is closer to the lens than the focal length B) The lens in the magnifying glass is converging C) The lens in the magnifying is diverging D) The book is further away from the lens than the focal length E) The image is a “real image” (i.e. not virtual).
A convex mirror produces a virtual image that is one quarter the size of the object. (a) Determine the image distance if the object is 37.0 cm in front of the mirror. (Include the appropriate positive or negative sign.) cm (b) Determine the focal length of the mirror. (Include the appropriate positive or negative sign.) cm A convex mirror produces a virtual image that is one quarter the size of the object. cm (b) Determine the focal length of the...
All rays that are parallel to the principle axis in a concave mirror reflects Select one: O a. Towards the focal point O b. Away from the focal point O c. Away from the center of curvature O d. Towards the center of curvature Which statements are true about a VIRTUAL image? (There may be more than one correct choice.) Select one or more: a. A concave lens always forms a virtual image. b. It cannot be photographed. c. A...
Q3. A 5-cm-high, upright virtual image is produced when an object is placed 12 cm from a converging lens (magnifying glass) with a focal length of 11 cm. Calculate the height of the object. (Read Ex13.7 on textbook)
For the last question is the image upright, downward, virtual, or real? PRACTICE IT Use the worked example above to help you solve this problem. An object 2.56 cm high is placed 20.8 cm from a convex mirror with a focal length of 8.10 cm. (a) Find the position of the image. -5.829 cm (b) Find the magnification of the mirror. 0.28 (c) Find the height of the image. 0.716 cm EXERCISE HINTS: GETTING STARTED I'M STUCK! Suppose the object...
Select from the following for the next question: A virtual, inverted and smaller than the object B real, upright and larger than the object C real, inverted and smaller than the object D real, upright and smaller than the object E virtual, upright and smaller than the object F virtual, inverted and larger than the object G real, inverted and larger than the object H virtual, upright and larger than the object An object is placed 6.4 cm away from...
Select the true statements about reflection from a plane mirror Select one or more: a. An image is only formed if the angle of incidence is less than the critical angle b. The image is the same distance behind the mirror as the object is in front c. The image is a "virtual image" d. The image is a "real image"
