Question

What would be the magnification of a specimen viewed with a compound light microscope that has an objective power of 10x and an ocular lens power of 5x?

Answer 1

(define (magnify specimen) ((lambda (x y) (* x y)) (10 specimen)))

Answer 2

10 x 5=50

Answer 3

any

Answer 4

(define square (lambda (x) (* x x)))
(define (average x y) (/ (+ x y) 2))
(define (sqrt x)
(define (improve guess)
(average guess (/ x guess)))
(define (good-enough? guess)
(< (abs (- (square guess) x))
.0001))
(define (try guess)
(if (good-enough? guess)
guess
(try (improve guess))))
(try 1))
