To find the value of the de Broglie wavelength in terms of its mass m and Planck's constant h, we start by letting the wavelength of the given particle be x. According to the problem, the velocity v is given by: v=‌
x
100
Using the de Broglie wavelength formula, we have: λ=‌
h
mv
Substituting the given velocity into the formula: x=‌
