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 will be the power of convex lens having a focal length is 50 cm?
Convert the focal length to meters, then take the reciprocal. That is how the "power" of a lens is calculated.
Whats the focal length of a lens?
The focal length of a lens is the distance from the principal foci to the center of the lens.
What is the power of a convex lens with 10cm focal length?
1.0 diopters
Why a small focal length convex lens is used in simple microscope?
because manifying power has inerse relation with that of focal length
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
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 will be the power of convex lens having a focal length is 50 cm?
Convert the focal length to meters, then take the reciprocal. That is how the "power" of a lens is calculated.
How do you find the power of a lens?
The power of a lens is 1/focal length (measured in meters).
A concave lens is kept in contact with convex lens of focal length 20cm the combination works as a converging lens of focal length 100cmcalculate the power of concave lens?
i think it is -0.06m i.e. 6cm
How do you find power of a power?
The power of a lens is 1/focal length (measured in meters).
Whats the focal length of a lens?
The focal length of a lens is the distance from the principal foci to the center of the lens.
What is the power of a convex lens with 10cm focal length?
1.0 diopters
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!
Why a small focal length convex lens is used in simple microscope?
because manifying power has inerse relation with that of focal length
How do you calculate magnification?
Divide the focal length of the objective lens by the focal length of the eyepiece.
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.
