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
What is the limit of the object distance to produce a real image?
The limit of the object distance to produce a real image is twice the focal length of the lens or mirror. This occurs when the object distance is equal to the focal length, resulting in the image distance being at infinity. At distances greater than twice the focal length, the real image becomes smaller and inverted.
If an object is placed at a distance greater than twice the focal length of a convex lens what type of an image will be produced?
If an object is placed at a distance greater than twice the focal length of a convex lens, a real and inverted image will be produced. The image will also be smaller than the object.
How are images produced by the convex lens of a magnifying glass are affected by focal length?
The focal length of a convex lens determines the magnification of the image produced by the magnifying glass. A shorter focal length will result in a larger magnification, making the image appear bigger. Conversely, a longer focal length will result in a smaller magnification, making the image appear smaller.
What is the relation of focal length of eye with its curvature?
The curvature of the eye's lens is related to its focal length: a more curved lens will have a shorter focal length, which allows the eye to focus on near objects. Conversely, a less curved lens will have a longer focal length, allowing the eye to focus on distant objects.
What will decreasing a telescope's eyepiece focal length?
The magnification of the telescope image is(focal length of the objective) divided by (focal length of the eyepiece).The focal length of the objective is fixed.Decreasing the focal length of the eyepiece increases the magnification of the image.(But it also makes the image dimmer.)
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

How does the ccd affect focal length in lens of the camera?
In a camera, the focal length of the lens determines the angle of view and the magnification of the image projected onto the sensor or CCD (Charge-Coupled Device). A larger focal length results in a narrower field of view and greater magnification, while a shorter focal length offers a wider field of view. The size of the CCD also influences the effective focal length; for instance, a smaller sensor can make a lens appear to have a longer focal length due to the crop factor. Thus, both the lens's focal length and the CCD size work together to shape the final image capture.
For a research telescope (with a long focal length) would the thickness be greater or less than for a backyard telescope (with a short focal length)?
Technically the shorter the focal length, the thicker the mirror. But some short focal length telescopes have relatively thin mirrors all the same.
How are images produced by the convex lens of a magnifying glass are affected by focal length?
The focal length of a convex lens determines the magnification of the image produced by the magnifying glass. A shorter focal length will result in a larger magnification, making the image appear bigger.

Do more curved lenses have smaller focal lengths?
No, the focal length of a lens depends on its shape and material properties rather than its curvature. A more curved lens may or may not have a smaller focal length depending on the specific design and purpose of the lens.
Will the focal length be greater in a thick or thin convex lens?
The focal length will be greater in a thin convex lens compared to a thick convex lens. Thinner lenses have less curvature, causing light rays to converge more gradually and thus increasing the focal length.
Which lens provides more magnification-a low power or a high power?
A lens of short focal length has a greater power (than a lens of large focal length)
Is a lens of 50 mm focal length or 5 cm focal length better to read a dictionary?
5cm and 50mm are the same thing.
