Structure of Atom question

2021 · 25 Jul · Shift 1 · Q17

JEE MainChemistryStructure of AtomNumerical+4 / −1
A source of monochromatic radiation of wavelength 400 nm provides 1000 J of energy in 10 seconds. When this radiation falls on the surface of sodium, x ×\times× 1020 electrons are ejected per second. Assume that wavelength 400 nm is sufficient for ejection of electron from the surface of sodium metal. The value of x is ‾\underline{\hspace{2cm}}​. (Nearest integer) (h = 6.626 ×\times× 10 −-− 34 Js)
