142155 When light of wavelength $300 \mathrm{~nm}$ falls on a photoelectric emitter, photoelectrons are liberated. For another emitter, however light of $600 \mathrm{~nm}$ wavelength is sufficient for creating photoemission. What is the ratio of the work functions of two emitters.
142156 The threshold frequency of the metal of the cathode in a photoelectric cell is $1 \times 10^{15} \mathrm{~Hz}$. When a certain beam of light is incident on the cathode, it is found that a stopping potential 4.144V is required to reduce the current to zero. The frequency of the incident radiation is
