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

wolverine [178]

Answer:

$\lambda=10^{-10}\ m$

Step-by-step explanation:

Given that,

The frequency of x-rays, $f=3\times 10^{18}\ Hz$

We need to find the wavelength for x-rays. The relation between wavelength, frequency and speed of light is given by :

$v=f\lambda\\\\\lambda=\dfrac{c}{f}\\\\\lambda=\dfrac{3\times 10^{8}}{3\times 10^{18}}\\\\=10^{-10}\ m$

So, the wavelength for x-rays is $10^{-10}\ m$ .
