Find the wavelength of the electromagnetic radiation with a frequency of 3x10^-18Hz (Show Work)

aalyn [17]

Answer:

λ = 1×10²⁶m

Explanation:

Given data:

Wavelength of radiation = ?

Frequency of radiation = 3×10⁻¹⁸Hz

Solution:

Formula:

c = f × λ

c = speed of wave = 3×10⁸ m/s

by putting values,

3×10⁸ m/s = 3×10⁻¹⁸Hz × λ

λ = 3×10⁸ m/s / 3×10⁻¹⁸s⁻¹

λ = 1×10²⁶m
