Light of wavelength 0 6 μm from a sodium lamp falls on a photocell and causes the emission of photoelectrons - Physics - Dual Nature Of Radiation And Matter

Question

Light of wavelength 0 6 μm from a sodium lamp falls on a
photocell and causes the emission of photoelectrons for which the
stopping photoelectrons potential is 0 5 V With light of wavelength
0 4 μm from a sodium lamp, the stopping potential is 1 5V With
this data, the value of h/e is?

value of h/e is 4×10−154×10−15 Vs

Light of wavelength 0.6 μm from a sodium lamp falls on a photocell and causes the emission of photoelectrons for which the stopping photoelectrons potential is 0.5 V. With light of wavelength 0.4 μm from a sodium lamp, the stopping potential is 1.5V. With this data, the value of h/e is?
