A lens having focal length f and aperture of diameter d forms an image...
Focal length will remain same whereas intensity will become 3I/4..because intensity is directly proportional to (aperture)^2 so new intensity will be I/4 and when we compare it with earlier intensity. it will reduce to 3I/4...Hope u will get it...
