Hello there.

High frequency X-rays have _____ wavelengths compared to visible light.

d) short

Answer: X rays have a short wavelength.

Explanation :

The wavelength of the x rays is, λ₁ = 0.01 nm to 10 nm

The wavelength of the visible light is, λ₂ = 380 nm to 750 nm

The frequency is inversely proportional to the wavelength of light i.e. [tex]\lambda\propto \dfrac{1}{\nu}[/tex]

So, the high-frequency x-rays have a short wavelength as compared to visible light.  

Hence, the correct option is (d) " short ".
