A particle X moving with a certain velocity has a debroglie wave length of 1Å, If the particle Y has a mass of 25% that of X and velocity 75% that of X, debroglies wave length of Y will be:
Text Solution
Verified by ExpertsB
Step 1. Given data:
The de-Broglie wavelength of 
.
Mass of 
mass of 
Velocity of 
mass of 
Step 2. Formula used:
De Broglie wavelength 
, where 
plank's constant, 
are mass and velocity respectively.
Step 3. Calculations:
Also, 
, (By putting the values of 
)
Thus, 
, (By putting the value of 
)
Hence, de Broglie's wavelength of 
will be 
.
