Question

If there is an increase in linear dimensions of the objects, the associated de-broglie wavelength.

• A. Increases
• B. Decreases
• C. Remains unchanged
• D. Depends on the density

Answer 1

The correct option is B Decreases

As we know,

By de Broglie wavelength equation,

Wavelength $=$ plank's constant $÷$ linear moment

i.e. wavelength $\left(h\right)\alpha \frac{1}{{\left(P\right)}_{momentum}}$

If mass is increases momentum increases than de Broglie wavelength decreases.
