Calculate the wavenumber $\bar{v}$ in $cm^{-1}$ for yellow radiation having a wavelength of $5800 \ \mathring{A}$.

Linear spectrum (line spectrum) is a characteristic of which of the following?

$A$ metal surface emits photoelectrons when the incident radiation possesses a minimum.....

$750$ waves of an energy radiation pass in one minute from a point. What will be the wavelength of the radiation? (Assume the speed of radiation is $3 \times 10^8 \ m/s$)

The Vijayawada $FM$ radio station broadcasts at a frequency of $103.4 \ MHz$. The wavelength of the corresponding radio waves (in $m$) is

Electrons are emitted with zero velocity from a metal surface when it is exposed to radiation of wavelength $8000 \ \mathring{A}$. What should be the maximum velocity of emitted electron when the same metal surface is exposed to radiation of wavelength $5000 \ \mathring{A}$? $\left( h = 6.6 \times 10^{-34} \ J \cdot s, \ m_e = 9.1 \times 10^{-31} \ kg, \ c = 3 \times 10^8 \ m/s \right)$
