As You Know ,
De Brogli Equation :
λ = h/mv
λ = h/P....(1)
Let P0 be the initial Momentum and P is the decrease in momentum .
When wavelength changed by 0.5%
λ + 0.5λ/100 = h/P0-P
100.5λ/100 = h/P0-P----(2)
By 1 and 2
P0 = 1.99P
De Brogli Equation :
λ = h/mv
λ = h/P....(1)
Let P0 be the initial Momentum and P is the decrease in momentum .
When wavelength changed by 0.5%
