Previous Year Question For Dual Nature of Matter and Radiation

Light with an average flux of 20 W/cm² falls on a non – reflecting surface at normal incidence having surface area 20 cm². The energy received by the surface during time span of 1 min is :
Light of frequency 1.5 times the threshold frequency is incident on a photosensitive material. What will be the photoelectric current if the frequency is halved and intensity is doubled?
An electron is accelerated from the rest through a potential difference of V volt. If the de Brogile wavelength of the electron is $1.227 \times 10^{-2}nm$ the potential difference is:
