Multiple choice

If electron, hydrogen, helium and neon nuclei are moving with the velocity of light, then the appropriate order of corresponding wavelengths will be

  1. electron > neon > helium > hydrogen

  2. neon > helium > hydrogen > electron

  3. hydrogen > electron > helium > neon

  4. helium > hydrogen > electron > neon

  5. electron > hydrogen > helium > neon

E Correct answer
Explanation

Wavelength is inversely proportional to the mass of the particle. The masses of these nuclei follow the order: electron>hydrogen>helium>neon
