Question

The MRI (magnetic resonance imaging) body scanners used in hospitals operate with 400 MHz radio frequency.The wavelength corresponding to this radio frequency is (A) 0.75 m (B) 0.75 cm (C) 1.5 m (D) 2 cm

Tardigrade Admin · Accepted Answer

λ=(c/v) =(3×108/400×106) =0.75 m

Q. The $MR I$ (magnetic resonance imaging) body scanners used in hospitals operate with $400 M Hz$ radio frequency.The wavelength corresponding to this radio frequency is

$0.75 m$

$0.75 c m$

$1.5 m$

$2 c m$

$λ = \frac{c}{v} = \frac{3 \times 1 0 ^{8}}{400 \times 1 0 ^{6}} = 0.75 m$
