photon
意味: A particle representing a quantum of light or other electromagnetic radiation, having no mass and travelling at the speed of light.
Photons are the carriers of electromagnetic force. They exhibit wave-particle duality — behaving as both waves and particles depending on how they are observed. Different energies of photons correspond to different types of electromagnetic radiation, from radio waves (low energy) to gamma rays (high energy). Visible light occupies a narrow band in this spectrum. Photons are key to technologies such as solar panels, lasers, and fibre-optic communications.
例文
- Solar panels convert photons from sunlight into electrical energy. 太阳能电池板将阳光中的光子转化为电能。Los paneles solares convierten los fotones de la luz solar en energía eléctrica.太陽光パネルは太陽光の光子を電気エネルギーに変換する。태양광 패널은 햇빛의 광자를 전기 에너지로 변환한다.
- A laser produces a concentrated beam of photons that are all the same wavelength and in phase. 激光产生一束集中的光子束,所有光子具有相同的波长且保持同相位。Un láser produce un haz concentrado de fotones que tienen la misma longitud de onda y están en fase.レーザーは同じ波長で位相の揃った光子の集中ビームを生成する。레이저는 동일한 파장과 위상을 가진 광자의 집중 빔을 생성한다.
- Fibre-optic cables transmit data as pulses of photons over vast distances with minimal signal loss. 光纤电缆以光子脉冲的形式传输数据,可在极长距离内保持极低的信号损耗。Los cables de fibra óptica transmiten datos como pulsos de fotones a grandes distancias con una pérdida de señal mínima.光ファイバーケーブルは光子のパルスとしてデータを伝送し、非常に長い距離でも信号損失を最小限に抑える。광섬유 케이블은 광자의 펄스 형태로 데이터를 전송하며, 매우 먼 거리에서도 신호 손실을 최소화한다.
