As de-Broglie wavelength, λ=(h/m v) So tor constant velocity λ propto (1/m) So, lesser will be the mass greater will be its de-Broglie wavelength.

Q. Assertion : The de-Broglie wavelength equation has significance for any microscopic and submicroscopic particles.
Reason :de-Broglie wavelength is inversely proportional to the mass of the object its velocity is constant.

If both the assertion and reason are true and reason explains the assertion.

If both the assertion and reason are true but reason does not explain the assertion.

If assertion is true but reason is false.

If assertion is false but reason is true.

As de-Broglie wavelength, $λ = \frac{h}{m v}$
So tor constant velocity $λ \propto \frac{1}{m}$
So, lesser will be the mass greater will be its de-Broglie wavelength.
