Human vision normally covers an angle of about 40° horizontally. A "normal" camera lens then is defined as follows: When focused on a distant horizontal object which subtends an angle of 40, the lens produces an image that extends across the full horizontal extent of the camera's light-recording medium (film or electronic sensor). Part A Determine the focal length f of the "normal" lens for a 35-mm camera that records images on film 36 mm wide. Express your answer using two significant figures. 195| ΑΣΦ 4 A Submit f= My Answers Give Up Submit Part B Determine the focal length of the "normal" lens for a digital camera that records images on a charge-coupled device (CCD) 1.00 cm wide.
