Question

Va rog ma poate ajuta cinevaaa? Am nevoie URGENT de ajutor!! (*problema2*)

Answer 1

1/x₂-1/x₁=1/f

1/x₂'-1/x₁=1/f'

_________"-"

1/x₂'-1/x₂=1/f'-1/f

1/f=(n₀-1)(1/R₁-1/R₂)

1/f'=(n₀/n-1)(1/R₁-1/R₂)

_______________":"

f'/f=(n₀-1)n/(n₀-n)=>f'=(n₀-1)nf/(n₀-n)=(1,53-1)*1,33*10/(1,53-1,33)=0,53*13,3/0,2=7,049/0,2=35,24 cm
