Question
Which one of the following have minimum wavelength
✓
Answer
(b) cosmic Rays $10^{-14} \mathrm{m}$ to $10^{-12} \mathrm{m}$
$\gamma$ Rays $10^{-12} m$ to $10^{-10} m$
$x$ Rays $10^{-10} \mathrm{m}$ to $10^{-09} \mathrm{m}$
Ultraviolet Rays $10^{-07} \mathrm{m}$ to $4 \times 10^{-07} \mathrm{m}$
Hence, cosmic Rays have smallest wavelength.
