Iwill give !me ! use the de broglie's wave equation to find the wavelength of a 2.00 g ball moving at 2 m/s. show your work. note: h = plank's constant (6.62607 x 10-34 j s)

de Broglie's wave equation describes that particles have wave properties.

Equation is 
    λ = h/mv

Where λ  is the wave length of the particle (m), h is the Planck's constant (6.62607 x 10⁻³⁴J s), m is the mass of a particle (kg) and v is the velocity (m/s).

λ = ?
h = 6.62607 x 10⁻³⁴ J s
m = 2.00 g = 0.002 kg
v = 2 m/s

By substitution,
    λ  = 6.62607 x 10⁻³⁴ J s / (0.002 kg x 2 m/s)
    λ  = 1.66 x 10⁻³¹ m

Hence, the wavelength of the 2.00 g ball is 1.66 x 10⁻³¹ m.

They are like other investigations? say there was a murder u have to do blood test and finger prints which run through a lab.
