2. Masala.
Linzaning fokus masofasi 5 sm. Uning optik kuchini toping.
Berilgan: Formula: Yechilishi:
F = 5 sm = 0,05 m D = 1/F D = 1/0,05 m = 20 dptr
D = ?
Javob: D = 4 dptr
3. Masala.
Linzaning fokus masofasi 10 sm. Uning optik kuchini toping, kattalashtirishini toping.
Berilgan: Formula: Yechilishi:
F = 10 sm = 0,1 m D = 1/F D = 1/0,1 m = 10 dptr
D
0
= 25 sm = 0,25 m K = D
0
/ F K = 0,25 m / 0,1 m = 2,5 marta
