When an electron jumps directly from an orbit of n = 4 to n = 2,

Yeah the correct answer is 𝙤𝙥𝙩𝙞𝙤𝙣 𝘽

When an electron moves from a 𝙝𝙞𝙜𝙝𝙚𝙧 𝙚𝙣𝙚𝙧𝙜𝙮 𝙡𝙚𝙫𝙚𝙡 (n = 4) to a 𝙡𝙤𝙬𝙚𝙧 𝙚𝙣𝙚𝙧𝙜𝙮 𝙡𝙚𝙫𝙚𝙡 (n = 2), it 𝙡𝙤𝙨𝙚𝙨 energy. This lost energy is released as a 𝙥𝙝𝙤𝙩𝙤𝙣 (light energy), meaning a photon is 𝙚𝙢𝙞𝙩𝙩𝙚𝙙.

But why not 2 photons since it moves from 4 to 2?
This is because electron is making 𝙤𝙣𝙚 𝙙𝙞𝙧𝙚𝙘𝙩 𝙟𝙪𝙢𝙥 from 𝙣 = 4 to 𝙣 = 2, so only 𝙤𝙣𝙚 𝙥𝙝𝙤𝙩𝙤𝙣 is emitted. (No wonder the question says "𝙟𝙪𝙢𝙥𝙨 𝙙𝙞𝙧𝙚𝙘𝙩𝙡𝙮")
