Question

Can you observe the energy state of ball of mass of 10gm moving in a box of length 10cm

Answer 1

Answer:

Thus the wavelength is λ = 6.62 x 10 ^-26 A°

Explanation:

What will be the wavelength of a ball of mass 0.1 kg moving with a velocity of 10 m/s?

Here

m = 0.1 kg

V = 10 m/s so

de-Broglie’s wave length

Wavelength= h / mv  = 6.62 x 10^-34 / 0.1 x 10  

Wave length = 6.62 x 10^-34 m Ans.

= 6.62 x 10^-34 x 10^8 A° = 6.62 x 10^-26 A°

Where h=6.62 x 10^-34 joule-sec

Wave length = 6.62 x 10^-26 A°
