Plz ans this questions
Well, well, well... If you want to turn reality into fiction and make that image virtual, you'll have to choose option d) - moving the object from outside the focal length of a converging lens to inside the focal length. It's like transporting the object of your desire into a twisted, imaginary realm. Just like teleportation, but for photons! Enjoy the surreality!
To determine which adjustment would cause an image to change from real to virtual, we need to understand the behavior of converging and diverging lenses.
Converging lenses, also known as convex lenses, are thicker at the center and converge parallel rays of light. They have a positive focal length. On the other hand, diverging lenses, also known as concave lenses, are thinner at the center and cause parallel rays of light to spread out. They have a negative focal length.
When an object is placed in front of a lens, the image formed can be either real or virtual. A real image is formed when the light rays actually converge at a specific location and can be projected onto a screen, while a virtual image appears to form at a location where the light does not actually converge, and cannot be projected onto a screen.
Let's examine each option to determine which adjustment would cause the image to change from real to virtual:
a) Moving the object from the focal point of a converging lens to a position inside the focal length:
When an object is placed at the focal point of a converging lens, the rays of light come out parallel, resulting in a parallel beam. In this scenario, no image is formed because the light rays do not converge. So, moving the object from the focal point of a converging lens to a position inside the focal length will not create any image.
b) Moving the object from the focal point of a diverging lens to a position inside the focal length:
In a diverging lens, the rays of light spread out after passing through the lens. When an object is placed at the focal point of a diverging lens, the outgoing rays are parallel. Therefore, no image is formed in this case as well. Therefore, moving the object from the focal point of a diverging lens to a position inside the focal length will not create any image.
c) Moving the object from outside the focal length of a diverging lens to inside the focal length:
When an object is placed outside the focal length of a diverging lens, the rays of light refract and spread out. As a result, a virtual image is formed on the same side as the object. Therefore, moving the object from outside the focal length of a diverging lens to inside the focal length will change the image from real to virtual.
d) Moving the object from outside the focal length of a converging lens to inside the focal length:
When an object is placed outside the focal length of a converging lens, the rays of light converge to form a real image on the opposite side of the lens. Hence, moving the object from outside the focal length of a converging lens to inside the focal length will not change the image from real to virtual.
Based on this analysis, the correct answer is option c) - moving the object from outside the focal length of a diverging lens to inside the focal length.
