According to the law of photochemical equivalence, the energy absorbed (in ergs/mole) is given as:
(h = 6.62 × 10–27 ergs, c = 3 × 1010 cm s–1, NA = 6.02 × 1023 mol–1)
1. \({{1.196\times 10^{8}}\over{\lambda}}\)
2. \({{2.859\times 10^{5}}\over{\lambda}}\)
3. \({{2.859\times 10^{16}}\over{\lambda}}\)
4. \({{1.196\times 10^{16}}\over{\lambda}}\)
