english: What you're seeing when you put it through a prism is that you heat hydrogen up and it doesn't just glow like a white light, it just emits light at particular colors, a red one, a light blue one, some dark blue ones.
non_english: Ono što vidite kad propustite ovu sliku kroz prizmu ja da ste zagrejali hidrogen i da on ne samo što svetli kao bela svetlost, nego i emituje svetlost tačno odredjenih boja, crvenu, svetlo plavu, neke tamno plave.
