Question

What is the wavelength of an electromagnetic wave that has a frequency of

Answer 1

The wavelength of an electromagnetic wave that has a frequency of 1.82 x 10¹⁸ Hz in a vacuum is 1.65 × $10^{-10}$m.

How to calculate wavelength?

The wavelength of a wave can be calculated by dividing the speed of the wave by its frequency.

According to this question, a wave has a frequency of 1.82 x 10¹⁸ Hz in a vacuum and speed of light in a vacuum is 3.00 × 10⁸ m/s.

λ = $\frac{v}{f}$

Wavelength (λ) = 3 × 10⁸ ÷ 1.82 × 10¹⁸

Wavelength (λ) = 1.65 × $10^{-10}$ m

Therefore, the wavelength of an electromagnetic wave that has a frequency of 1.82 x 10¹⁸ Hz in a vacuum is 1.65 × $10^{-10}$m.
