Which of the following term is not associated with a lens?
Which of the following term is not associated with a lens?
The correct option is B Efficiency
The explanation for the correct option:
Efficiency:
The ability to produce something with the least amount of effort is defined as efficiency.
Hence, Option(B) is correct.
The explanation for incorrect options:
Focal length:
When the subject is in focus, the focal length of the lens is the distance between the lens and the image sensor.
The radius of curvature:
The center of curvature of a spherical lens or mirror surface is either along or decentered from the system's local optical axis.
Myopia:
Nearsightedness (myopia) is a common vision condition in which you can clearly see objects close to you but not those farther away. It happens when your eye's shape causes light rays to bend (refract) incorrectly, focusing images in front of your retina rather than on your retina.
.Hence, Options (A),(C) and (D) are incorrect.
Hence, Option(B) is correct.
