What is the wavelength of gamma ray electromagnetic radiation with a frequency of 2.73x10^20 Hz?
Amanda [17]

Answer:

1.10 × 10⁻¹² m

General Formulas and Concepts:

<u>Chemistry - Atomic Structure</u>

Speed of Light = Wavelength times Frequency

  • c = λν
  • c = 3.0 × 10⁸ m/s

Explanation:

<u>Step 1: Define</u>

ν  = 2.73 × 10²⁰ Hz

<u>Step 2: Find wavelength</u>

3.0 × 10⁸ m/s = λ(2.73 × 10²⁰ Hz)

λ = 1.0989 × 10⁻¹² m

<u>Step 3: Check</u>

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

1.0989 × 10⁻¹² m ≈ 1.10 × 10⁻¹² m
