Question

X-rays are electromagnetic waves used to obtain images of bones. An x-ray machine produces x-ray waves with a frequency of 1.25 x 10^18 Hz.
(a) Calculate the time period of these x-rays.

Answer 1

Answer:

$T=8\times 10^{-19}\ s$

Explanation:

Given that,

The frequency of x-ray is, $f=1.25\times 10^{18}\ Hz$

We need to find the time period of these x-rays. Let it is be T. We know that, the relation between f and T is given by :

T = 1/f

So,

$T=\dfrac{1}{1.25\times 10^{18}}\\\\=8\times 10^{-19}\ s$

So, the time period of these x-rays is equal to $8\times 10^{-19}\ s$.
