Acamera phone called the iphone x has an image sensor size of 5 mm and a focal length of 4 mm. how long of a selfie-stick must you use to take a picture of you and liz cambage of the las vegas aces who stands at 2.032 meters and not be cropped (i. e., the image size can't exceed 5 mm)?

length of selfie-stick is 1.62 m

Explanation:

Given data

image size h1 = 5 mm = 5 × m

focal length = 4 mm = 4 × m

distance h2 = 2.032 m

to find out

How long of a selfie-stick

solution

here we find first magnification

that is M = h1 /h2

M = 5 × / 2.032

M = 2.46 ×

and we know M = p/q

so p = Mq = 2.46 × q

so we apply lens formula

1/f = 1/p - 1/q

1/ 4 × = 1 / 2.46 ×  q - 1/q

q = 1.622 m

so length of selfie-stick is 1.62 m

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
