Question

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

Answer 1

Answer:

1.10 × 10⁻¹² m

General Formulas and Concepts:

Chemistry - Atomic Structure

Speed of Light = Wavelength times Frequency

• c = λν
• c = 3.0 × 10⁸ m/s

Explanation:

Step 1: Define

ν  = 2.73 × 10²⁰ Hz

Step 2: Find wavelength

3.0 × 10⁸ m/s = λ(2.73 × 10²⁰ Hz)

λ = 1.0989 × 10⁻¹² m

Step 3: Check

We are given 3 sig figs. Follow sig fig rules.

1.0989 × 10⁻¹² m ≈ 1.10 × 10⁻¹² m
