Which is having a minimum wavelength?

Which is having a minimum wavelength?

Options

  1. AX-rays
  2. BUltraviolet rays
  3. Cγ\gamma-rays
  4. DCosmic rays

Correct answer

D. Cosmic rays

Step-by-step solution

Cosmic rays, having very short wavelength. Wavelengths →\rightarrow X\mathrm{X}-ray ⇒1A˚\Rightarrow 1 Å to 100A˚100 Å Ultraviolet rays →100A˚\rightarrow 100 Å to 1A˚1 Å V-rays →0.001A˚\rightarrow 0.001 Å to 1A˚1 Å Cosmic rays →\rightarrow upto 4×10−3A˚4 \times 10^{-3} Å
