According to the wave-particle duality of matter by de-Broglie, which of the following graph plot presents most appropriate relationship between wavelength of electron $$\lambda$$ and momentum of electron $$p$$? (Four graphs are shown: (1) $$\lambda$$ vs $$p$$ showing a rectangular hyperbola, (2) $$p$$ vs $$\lambda$$ showing a rectangular hyperbola, (3) $$\lambda$$ vs $$1/p$$ showing a straight line through origin, (4) $$\lambda$$ vs $$p$$ showing a straight line with negative slope)
