The velocity of X-ray is the velocity -c- of light-xA0-Thus- wavelength of an X-ray- -x3BB-cf-3-xD7-1081018-3-xD7-10-x2212-10m

Calculate the wavelength of an X-ray whose frequency is 1.0×1018Hz.3.3×10−11m3.0×10−8m3.0×1026m3.0×10−10m3.3×10−9m

The velocity of X-ray is the velocity (c) of light. Thus, wavelength of an X-ray, λ=cf=3×1081018=3×10−10m

Calculate the wavelength of an X-ray whose frequency is $1.0 \times 10^{18} H z$ .
$3.3 \times 10^{- 11} m$
$3.0 \times 10^{- 8} m$
$3.0 \times 10^{26} m$
$3.0 \times 10^{- 10} m$
$3.3 \times 10^{- 9} m$

The velocity of X-ray is the velocity (c) of light.
Thus, wavelength of an X-ray, $λ = \frac{c}{f} = \frac{3 \times 10^{8}}{10^{18}} = 3 \times 10^{- 10} m$
