MHT CET · Physics · Dual Nature of Matter
When the kinetic energy of an electron is increased the wavelength of the associated wave will
- A increase
- B decrease
- C wavelength does not depends upon kinetic energy
- D None of the above
Answer & Solution
Correct Answer
(B) decrease
Step-by-step Solution
Detailed explanation
\(\lambda=\frac{h}{\rho}=\frac{h}{\sqrt{2 m E}}\)
\(\therefore \quad \lambda=\frac{1}{\sqrt{E}}\)
\(\therefore \quad \lambda=\frac{1}{\sqrt{E}}\)
