Statement 1: According to de Broglie, the wavelengths associated with electrons and other subatomic particles can be detected experimentally.
Statement 2 : The wavelength associated with any material particle is directly proportional to its mass.

Options

A. If both (A) and (R) are correct and (R) is the correct explanation of(A).
B. If both (A) and (R) are correçt, but (R) is not the correct explanation of (A).
C. If (A) is correct, but (R) is incorrect.
D. If both (A) and (R) are incorrect.

Answer

C

Explanation

According to de Broglie equation, `lambda=(h)/(mv)`, hence wavelength is inversely proportional to mass of a particle and hence can be observed only for microscopic particles with very small mass.
