and sorry for my handwriting
plz correct if wrong
comment if correct

Answer 2

Answer:

$E=1.98\times 10^{-15}\ J$

Explanation:

Given that,

Wavelength of x rays, $\lambda=10^{-10}\ m$

We need to find the energy of x rays. The formula for the energy of x- rays is given by :

$E=\dfrac{hc}{\lambda}$

$E=\dfrac{6.63\times 10^{-34}\times 3\times 10^8}{10^{-10}}$

$E=1.98\times 10^{-15}\ J$

So, the energy of x rays is $1.98\times 10^{-15}\ J$. Hence, this is the required solution.
