What is the sign of the focal length for a diverging lens?
The sign of the focal length for a diverging lens is negative. This indicates that the focal point is located behind the lens where the light rays appear to diverge.
Which lens has a greater power convex lens of focal length 10 cm or a convex lens of focal length 20cm?
Power is inversely related to the focal length. So convex lens of focal length 20 cm has less power compared to that having focal length 10 cm
When it is within one focal length from the lens?
When an object is placed within one focal length from a lens, the image formed is virtual, upright, and magnified. This happens because the rays of light are diverging after passing through the lens.
A diverging lens always produces a reduced real image?
A diverging lens can produce both reduced and magnified real images, depending on the position of the object relative to the lens and the focal length of the lens. However, the most common case is for a diverging lens to produce a reduced real image.
When does convex lens act as a diverging lens?
A convex lens can act as a diverging lens when the object is placed very close to the lens, inside its focal length. In this situation, the light rays diverge after passing through the lens, causing the image to appear virtual and upright.

What direction does a focal ray from an object proceed after passing through a diverging lens?
After passing through a diverging lens, a focal ray will diverge away from the principal axis of the lens.
What is the lens focal length formula used to calculate the focal length of a camera lens?
The lens focal length formula used to calculate the focal length of a camera lens is: Focal Length (Distance between lens and image sensor) / (1 (Distance between lens and object) / (Distance between lens and object))
Length of a lens is the distance from the center of the lens to its principal focus?
It is called the focal length. It is equal to 1/2 times r, and is positive on concave mirrors and negative on convex mirrors.
The distance from lens to focal point is called?
The distance from a lens to the focal point is called the focal length.
What image can a diverging lens produce?
A diverging lens can produce several types of images, depending on the location of the object relative to the lens. Typically, a diverging lens will produce a virtual, upright, and reduced image for objects placed beyond the lens' focal point.
Explain how the focal length changes as a convex lens becomes flatter?
The focal length of a lens is the distance from the center of the lens to the point at which it focuses light rays. The bigger the focal length, the more powerful the lens. ChaCha!
Does the focal lens length have three classifications?
yes, focal lens length has three classifications
