What is the wavelength of an electromagnetic wave that has a frequency of 245 x 10 Hz in a vacuum The speed of light in a vacuum is 300 x 108 ma O A 817 m OB 12 class=

Respuesta :

Answer:

B

Explanation:

To calculate questions like this, you need to make use of the equation below:

ν = c / λ

ν is the frequency, c is the speed of light, and λ is the wavelength

ν = c / λ

2.45 • 10^9 Hz = (3•10^8 m/s)/(λ)

λ = 0.122 m = B
