Answer:
5.88 × 10⁻⁷ m
Explanation:
Speed of Light = Wavelength times Frequency
c = λν
Step 1: Define
c = 3.0 × 10⁸ m/s
ν = 5.10 × 10¹⁴ Hz
λ = unknown
Step 2: Solve for λ
3.0 × 10⁸ m/s = 5.10 × 10¹⁴ Hz · λ
λ = 5.88235 × 10⁻⁷ m
Step 3: Simplify
We are given 3 sig figs.
5.88235 × 10⁻⁷ m ≈ 5.88 × 10⁻⁷ m
