Answer:
v = 6.59 × 10¹⁰ Hz
Explanation:
Wavelength Formula: c = λv
Step 1: Define
c is the speed of light = 3.0 × 10⁸ m/s
λ is wavelength = 4.55 × 10⁻³ m
v is frequency in hertz
Step 2: Substitute and Evaluate for v
3.0 × 10⁸ = 4.55 × 10⁻³ · v
v = 6.59341 × 10¹⁰ Hz
Step 3: Simplify
We are given 3 sig figs.
6.59341 × 10¹⁰ Hz ≈ 6.59 × 10¹⁰ Hz
