The inverse variation equation shows the relationship between wavelength in meters, x, and frequency, y.

Vaselesa [24]

Answer: The wavelength for X-rays with the given frequency is $1\times 10^{-10}m$

Step-by-step 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 = $3\times 10^{18}s^{-1}$

Putting the values in above equation, we get:

$\lambda=\frac{3\times 10^8m/s}{3\times 10^{19}s^{-1}}=1\times 10^{-10}m$

Hence, the wavelength for X-rays with the given frequency is $1\times 10^{-10}m$
