Calculate the momentum of a particle which has a de Brglie wavelength of 1 Å or 0.1 nm. (h = 6.6 xx 10^(-34) kg m^(2) s^(-1))

Calculate the momentum of a particle which has a de Brglie wavelength

1.	Calculate the momentum of a particle which has a de Brglie wavelength of 1 Å or 0.1 nm. (h = 6.6 xx 10^(-34) kg m^(2) s^(-1))
Answer» SOLUTION :`lamda = (H)/(p) or p = (h)/(lamda) = (6.6 xx 10^(-34) kg m^(2) s^(-1))/(10^(-10)m) = 6.6 xx 10^(-24) kg m s^(-1) (1 Å = 10^(-10)m, 1NM= 10^(-9) m)`
