Question

X-rays and $\gamma$-rays both are electromagnetic waves. Which of the following statements is correct?

• A. The wavelength of X-rays is greater than that of $\gamma$-rays.
• B. The wavelength of X-rays reduce is less than that of $\gamma$-rays.
• C. The frequency of $\gamma$-rays is less than that of X-rays.
• D. The frequency and wavelength of X-rays are more than those of $\gamma$-rays.

Answer 1

Answer: (A)

The wavelength of X-rays is greater than that of $\gamma$-rays.

The energy of the x rays is less than that of $\gamma$ rays.
$E_{xrays}<E_{\gamma rays}$

$\frac{hc}{{\lambda }_{xrays}}<\frac{hc}{{\lambda }_{\gamma rays}}$

${\lambda }_{xrays}>{\lambda }_{\gamma rays}$
