18 Questions
For an object placed between 2F' and the convex lens, where is the image located?
Beyond 2F
In which case for convex lenses does the image always end up smaller than the object?
Case I
What happens to the size of the image formed by a concave mirror?
It is always larger than the object
When an object is placed at F' for a convex lens, what type of image is formed?
Virtual
In which type of lens does the image orientation always remain upright?
Convex lens
If an object is placed at infinity in front of a concave lens, what happens to the image?
No image is formed
What is the main purpose of a lens in optical devices like cameras and microscopes?
To refract light rays, causing them to converge or diverge
Which type of lens is thicker at the middle than at the rim?
Convex lens
How many focal points do converging and diverging lenses have each?
Two focal points each
In the lens equation, what does a positive value for 'di' indicate?
A real image
Where are virtual images seen in relation to the lens?
On the same side as the object
How can one determine the location of an image formed by a lens other than using ray diagrams?
Direct calculation using the lens equations
In Case I, where is the image located relative to the focal point (F), 2F, and the lens?
Beyond 2F
In Case II with a convex lens, what is the nature of the image when the object is located at 2F'?
Real and inverted
For Case III with a convex lens and an object located between 2F' and F', where is the image located?
At 2F
When an object is located at F' with a convex lens, where is the image located?
At F'
What happens to the size of the image in Case II compared to the original object?
Image size is larger
How does the orientation of the image in Case IV compare with that of the original object?
Image is inverted
Explore the positioning of images formed by mirrors and lenses in different scenarios including convex and concave lenses. Understand the characteristics of the images such as real or virtual, size, and orientation compared to the original object.
