Question

the MRI body scanners used in hospitals operate with 400 MHz radio frequency energy. what is the wavelength corresponding this radio frquency​

Answer 1

Answer:

I am sure it will help you

Explanation:

Answer 2

The wavelength corresponding this radio frequency​ is 0.75 m

Explanation:

To calculate the wavelength of light, we use the equation:

$\lambda=\frac{c}{\nu}$

where,

$\lambda$ = wavelength of the light  

c = speed of light = $3\times 10^8m/s$

$\nu$ = frequency of light = $400MHz=400\times 10^6Hz=400\times 10^6s^{-1}$

$\lambda=\frac{3\times 10^8m/s}{400\times 10^6s^{-1}}$

$\lambda=0.75m$

The wavelength corresponding this radio frequency​ is 0.75 m
