O`lchash natijalarni hisoblash 
(21) formuladan foydalanib istalgan m-nchi Nyuton qora haqasi radiusini 
hiosblash formulasi

Yuqorida aytganimizdek, istalgan halqaning diametri jadvaldagi o`ng va chap 
halqa vaziyatlarining ayirmasiga teng, ya`ni
(25) 
bunga asosan (24) quyidagicha yoziladi:
(26) 
(26) formulani quyidagicha yozamiz: 
(27) 
Bu yerda

Jadvaldagi o`lchashlarga asosan (27) formula yordamida eng kichik kvadratlar 
usuli bilan tenglama koeffisientlari A, B, m
o
, R-lar, ularning xatoliklari va nisbiy 
xatoliklari topiladi. m

– yoqolgan Nyuton halqalari soni yassi parallel shisha 
plastinka ustidagi yassi qavariq linza qattiq siqilib qo`yilgani uchun ikkala shisha 
ham deformatsiyalanadi. Shu sababdan, mikroskop ostida ko`ringan markaziy 
minimum nolinchi emas.
Millimetrli qog`ozga jadval ostida (26) formulaga binoan abtsissa o`qiga m

lar joylashtirib, garfik chiziladi va keyin o`sha grafik 
ustiga 
nazariy olingan grafik ham chizilib uar solishtiriladi. 
Grafikdan ham A va B koeffisientlar topiladi.
