However, where a previously absorbed line (first Lyman beta, ...) reaches Lyman alpha frequency, redshifting process stops and all hydrogen lines are strongly absorbed.
Porén, onde unha liña previamente absorbida (primeira Lyman beta, ...) alcanza a frecuencia Lyman alfa, o proceso de desprazamento ao vermello detense e todas as liñas do hidróxeno son fortemente absorbidas.
