Question

You observe 2 waves named alpha and beta. The alpha wave has a frequency of 5 Hz and the beta wave has a frequency of 2 Hz. Based on these observations which wave has a shorter wavelength? Group of answer choices

Answer 1

shorter wavelength = alpha wave

Step-by-step explanation:

Given that,

The alpha wave has a frequency of 5 Hz and the beta wave has a frequency of 2 Hz.

We need to compare the wavelengths of these two waves.

For alpha wave,

`\lambda_1=(c)/(f_1)\\\\\lambda_1=(3* 10^8)/(5)\\\\=6* 10^7\ m`

For beta wave,

`\lambda_2=(c)/(f_2)\\\\\lambda_2=(3* 10^8)/(2)\\\\=15* 10^7\ m`

From the above calculations, we find that the wavelength of the alpha wave is shorter than the wavelength of the beta wave.
