Answer 1

Diketahui :
d = 45μ m = 45 x10⁻⁶ m
l = 75 cm = 75 x10⁻² m
p = 1 cm = 10⁻² m
n = 1

ditanyakan :
λ = ?

jawab :
dp/l = m λ
45 x10⁻⁶ x 10⁻² / 75 x10⁻² = 1 λ
0,6 x10⁻⁶ = λ
6 x 10⁻⁷ m = λ
λ = 6000 A

Answer 2

Diket:
d= 45πm = 4,5.10⁻⁵ m
L= 75 cm = 0,75 m
y= 1 cm= 0,01 m
n= 1
dit: λ=...?
Jawab:
y=λ.L.n/.d
0,01= λ.0,75.1/.4,5.10⁻⁵
λ= 4,5.10⁻⁷/0,75.
λ= 4,5.10⁻⁷/0,75
λ= 6.10⁻⁷ m
λ= 6000 Amstrong
