Question

If the velocity of a particle is reduced to 1/3rd, then percentage increase in its de-Broglie wavelength will be​

Answer 1

The velocity of the partical is increased by 3 times

Reason : "Velocity" is inversely proportional to "Wavelength"

Answer 2

Answer:

200%

Explanation:

As we know lambda= h/mv

When v is reduced to V/3, we get

Lambda = h/mv/3 ( because V = V/3)

= 3h/mv

Increase in wavelength= 2h/mv

% Increase in wavelength=

2h/mv×mv/h× 100%

Mv and h cancels

Answer : 200%
