Sample questions
The De Broglie wavelength of a particle moving with a speed of $v = 1.0 \times 10^6 \text{ m/s}$ is $\lambda$. If the same particle's speed is increased to $2.0 \times 10^6 \text{ m/s}$, its new De Broglie wavelength will be $\lambda/X$. The value of $X$ is (Write the answer as an integer).
When a metallic surface is illuminated with radiation of wavelength λ the stopping po- tential is V. If the same surface is illumi- nated with radiation of wavelength 2λ the stopping potential is V 4, The threshold wave- length for the metallic surface is
A metal surface of work function 1.07 eV is irradiated with light of wavelength 332 nm. The retarding potential required to stop the escape of photo-electrons is
