Question details

(10%) Problem 7: Two lenses are mounted d 28 cm apart on an optical bench. The focal length of the first lens ish = 8.7 cm and that of the second lens is = 4.4 cm. An object of height h.-4.4 cm is placed at a distance of do-22 cm in front of the first lens 25% Part (a) Ignoring the second lens for now, at what distance, in centimeters, behind the first lens is the objects image formed by that lens? di Grade Summary Deductions 0% 100% cosO 78 9 Submissions Attempts remaining: 3 cotan)asin) acosO % per attempt) detailed view atan() acotan() sinhO coshOtanh cotanhO Degrees O Radians 12 3 0 END CLEAR SubmitHint I give up!
