Question

how change in velocity of a moving particle change the wavelength of the particle

Answer 1

The change in the velocity will change in the wavelength according to the deBroglie wavelength.
λ=hmv
Hence, Wavelength is inversely proportional to the velocity of the moving particle. If velocity will be increased, wavelength will be decreased.

Answer 2

According to De Broglie Wavelength velocity of a moving particle is inversely proportional to the wavelength of the particle. Due to this if velocity increses the wavelenth of particle will decrease and vice-versa.

(De Broglie Wavelength formula is given in attachments)
