Question

compared to visible light, the wavelength of x - rays is and the frequency is

Explanation:

In the electromagnetic - spectrum, X - rays have shorter wavelengths and higher frequencies compared to visible light. This is based on the inverse relationship between wavelength ($\lambda$) and frequency ($f$) given by the equation $c = f\lambda$, where $c$ is the speed of light in a vacuum. Since $c$ is constant, when $\lambda$ decreases, $f$ increases.

Answer:

Shorter; Higher
