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 power of 2 m focal lens?
The power of a lens is calculated as the reciprocal of its focal length in meters. Therefore, a 2 m focal length lens would have a power of 0.5 diopters.
What is the power of a convex lens with 10cm focal length?
The power of a lens is calculated as the reciprocal of its focal length in meters. Therefore, a convex lens with a 10 cm focal length has a power of +10 diopters.
What is the power of a convex lens whose focal length is 25 cm?
The power of a lens is the reciprocal of its focal length in meters. So, a lens with a focal length of 25 cm would have a power of +4 diopters (1/0.25 = 4).
How power and focal length related?
Power in optics is inversely proportional to the focal length of a lens. A lens with a shorter focal length will have greater optical power, while a lens with a longer focal length will have less optical power. This relationship is important in determining the strength and magnification of corrective lenses used in eyeglasses and contact lenses.

What is the power of a convex lens with 10cm focal length?
The power of a lens is calculated as the reciprocal of its focal length in meters. Therefore, a convex lens with a 10 cm focal length has a power of +10 diopters.
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)
What is the power of a convex lens whose focal length is 25 cm?
The power of a lens is the reciprocal of its focal length in meters. So, a lens with a focal length of 25 cm would have a power of +4 diopters (1/0.25 = 4).
What is the magnifing power of the lens?
Depends on your microscope. We've got one that's a x2.

What does curvature of radius of a lens effect?
The curvature of the radius of a lens affects its focal length and optical power. A lens with a shorter radius of curvature will have a shorter focal length and higher optical power, while a lens with a larger radius of curvature will have a longer focal length and lower optical power.
How do you find the power of a lens?
The power of a lens is 1/focal length (measured in meters).
What is the relation between power of lens and focal length?
n - 1D = --------rwhere:D = dioptric power of the surface,n = the index of the material that the surface is made from,r = the radius of curvature of the surface, in metersand where the surface is in air.
What will be the power of convex lens having a focal length is 50 cm?
The power of a lens is given by the formula P = 1/f, where f is the focal length in meters. Converting 50 cm to meters, we get f = 0.5 m. Therefore, the power of a convex lens with a focal length of 50 cm is P = 1/0.5 = 2 diopters.
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))
