Answer to Question #335471 in General Chemistry for MocyTech

Question

Calculate the wavelength of a particle with masses 9.11x10-31Kg travelling at speed 1.0x107 m/s and that of a ball of mass 0.1Kg travelling at 35 m/s. Comment on the significance of the wavelengths calculated.

Answer 1

1. Wavelength of a particle is 0.73×10^-10

2. Wavelength of a ball is 1.91×10^-34

Lighter particles have longer wavelengths as compared to the heavier ones, provided they both have same velocity.
