JEE Main 2025 Physics question

During the transition of electron from state A to state C of a Bohr atom, the wavelength of emitted radiation is 2000 Å and it becomes 6000 Å when the electron jumps from state B to state C. Then the wavelength of the radiation emitted during the transition of electrons from state A to state B is :-

• (1)3000 ÅCorrect
• (2)6000 Å
• (3)4000 Å
• (4)2000 Å
