A body of mass 200g moves at the speed of 5 m/hr. So de broglie wavelength related to it is of the order: (h=6.26 x 10^-34 Js)
Correct answer: C. 10-30 m
- A. 10-10 m
- B. 10-20 m
- C. 10-30 m
- D. 10-40 m
Explanation
m = 200g = 0.2kg v = 5m/hr = 5/3600 m/s P = h/λ = mv λ = h/mv = 6.626x10^-34x3600/0.2x5 = 23.85x10^-31 = 2.385x10^-30 = 10^-30m

About Dawn of Modern Physics
Classical physics cannot explain blackbody radiation and related observations, leading to Planck’s quantum theory, in which energy is emitted or absorbed in discrete packets. Photons provide the particle model of light, with energy and momentum linked to frequency and wavelength, including the photoelectric effect and its threshold frequency.
