Metal B has a lower threshold wavelength because threshold wavelength (λ th ) is inversely proportional to the work function (W) as λ th = hc/W . A higher work function results in a shorter threshold wavelength. For more visit here: https://www.tiwariacademy.com/ncert-solutions/class-12/physics/chapRead more
