For photoelectric emission, tungsten requires light of $ 2300 \mathring A$. If light of $1800 \mathring A $ wavelength is incident then emission

ATakes place
BDon’t take place
CMay or may not take place
DDepends on frequency

Solution

(a) In tungsten, photoemission take place with a light of wavelength $2300 \mathring A$. As emission of electron is inversely proportional to wavelength, all the wavelengths smaller then $2300 \mathring A$ will cause emission of electrons.
