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 lens of focal length 40cm?
The power of a lens is given by the formula P = 1/f, where f is the focal length of the lens. Therefore, for a lens with a focal length of 40cm, the power would be P = 1/40 cm = 0.025 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 do you find the power of a lens?
The power of a lens is 1/focal length (measured in meters).
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 do you find power of a power?
The power of a lens is 1/focal length (measured in meters).
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.
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 lens of focal length 40cm?
The power of a lens is given by the formula P = 1/f, where f is the focal length of the lens. Therefore, for a lens with a focal length of 40cm, the power would be P = 1/40 cm = 0.025 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).
Why focal length of convex lens is easier to find than a concave lense?
The focal length of a convex lens is easier to find than a concave lens because for a convex lens, the focal length is positive and is measured from the lens to the focal point. In contrast, for a concave lens, the focal length is negative and the rays of light are diverged. This makes it more challenging to find the focal point accurately.
What is the magnifing power of the lens?
Depends on your microscope. We've got one that's a x2.
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 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.
