Calculate the wavelength and momentum of α particle moving with a speed of 10^5cm/sec |
|
Answer» ! just LOOK at the solution. look velocity is GIVEN so we can easily CALCULATE momentum .I considered the mass of that particle to be'm'. So momentum =1000m.You have to change velocity in its SI units.now WAVELENGTH=h/mvthis formula is from debroglie HYPOTHESIS. after plugging all the values we get wavelength =6.626×10^-37/m.The value of planck's constant is 6.626×10-34. |
