Answer 2

$\boxed{\boxed{QuesTion}}$

Calculate the wavelength in NM of an X-ray wave of frequency 2.0 x10^18 Hz

$\boxed{\boxed{Answer:-}}$

Data:- v=2.0 x10^18 Hz Co=3.0 x 10^8 m/s

the wavelength of the x-ray wave

$= \frac{co}{v} = \frac{3.0 \times {10}^{8} }{2.0 \times {10}^{18} } = 1.5 \times {10}^{ - 8} m$

=0.15 x 10^-9 m

=$\boxed{\boxed{0.15 nm}}$
