Calculate the wavelength (in nanometer) associated with a proton moving at 1.0 × 103 m s–1 (Mass of proton = 1.67 × 10–27 kg and h = 6.63 × 10–34 Js) :

Question

Arun · Answer

As we learnt in De-broglie wavelength - - wherein where m is the mass of the particle v its velocity p its momentum

Vikas TU · Answer

Here,de-broglie wavelength. wavelenght=h/mv 200× 10^-12=6.626×10^-34/p[1pm=10^-12m,h=6.626×10^-34] p=6.626×10-34/200×10^-12 p=6.626×10-34/2×10^-10 p=3.313×10^-34+10 p=3.313×10^-24kgms-
