Question

The energy of the em waves is of the order of 15 keV. To which part of the spectrum does it belong?


A
γ rays

B
x rays

C
Infra - red rays

D
Ultraviolet rays

Solution

The correct option is A x rays
$$E=\dfrac{hc}{\lambda}$$
or $$\lambda=\dfrac{hc}{E}=\dfrac{(6.6\times 10^{-34})\times (3\times 10^8)}{15\times 10^3\times 1.6\times 10^{-19}}=0.8 \times 10^{-10}  m=0.8 {A^o}$$
So it is nearly related to the X-ray wavelength.
