Question

Consider the following statements:
1. According to de-Broglie hypothesis, particles have wave-like characteristics.
2. When an electron and proton have the same de-Broglie wavelength, they will have equal momentum.
Which of the statement(s) given above is/are correct?

• A. Only 1
• B. Only 2
• C. Both 1 and 2
• D. Neither 1 nor 2

Answer 1

The correct option is C Both 1 and 2

According to de-Broglie hypothesis, a wave is associated with matter suggesting particles have wavelike characteristics.
de-Broglie wavelength is given by $\lambda =\frac{h}{p}$
where $p$ is the momentum.
So, both electron and proton having same de-Broglie wavelength will have equal momentum.
