Answer:

λ = 6.25 × 10⁻¹⁰ m

x-ray

General Formulas and Concepts:

Speed of Light = Wavelength times Frequency

  • c = λν

Explanation:

<u>Step 1: Define</u>

C = 3.0 × 10⁸ m/s

ν  = 4.80 × 10¹⁷ Hz (s⁻¹)

λ = unknown

<u>Step 2: Solve for wavelength</u>

3.0 × 10⁸ m/s = λ(4.80 × 10¹⁷ Hz)

λ = 6.25 × 10⁻¹⁰ m

<u>Step 3: Check</u>

<em>We are given 3 sig figs. Follow sig fig rules.</em>

6.25 has 3 sig figs. No changes necessary.

<u>Step 4: Identify</u>

6.25 × 10⁻¹⁰ m is in the x-ray spectrum according the the Electromagnetic Spectrum
