Question

True statement with reference to matter waves is :

• A. These are electromagnetic waves.
• B. These are mechanical waves.
• C. Wavelength of these waves does not depend on charge of the particle.
• D. Velocity of matter waves is equal to velocity of light.

Hint:

Matter waves' wavelength is dependent on the momentum of the particle and not its charge.

Answer 1

The Correct Option is C

Step 1: Matter Waves and Their Characteristics.
Matter waves, described by de Broglie, are associated with particles and their wavelength is given by \( \lambda = \frac{h}{p} \), where \( h \) is Planck's constant and \( p \) is the momentum. The wavelength does not depend on the charge of the particle but on its momentum.

Step 2: Conclusion.
Thus, the correct statement is that the wavelength of matter waves does not depend on the charge of the particle. Therefore, the correct answer is option .
