无线电波是一种我们看不见的电磁辐射。
微波也是一种电磁辐射，这与阳光和无线电波都是非常相似的。
Microwaves are a form of electromagnetic radiation that is very similar to sunlight and radio waves.
威尔逊和彭齐亚斯捕捉人造卫星上反弹回来的无线电波的天线时不经意地发现了宇宙微波背景辐射，而这正是宇宙大爆炸的物理性证据。
And Wilson and Penzias discovered the cosmic microwave background radiation, physical evidence for the Big Bang, while fiddling with an antenna designed to catch radio waves bouncing off satellites.
手机辐射的光子聚集起来并不能成为紫外线，也不能具备与微波或无线电波的威力。
Cell phone photons cannot add up to become UV photons or have their effect any more than microwave or radio-wave photons can.
该卫星携带一台被动无线电波探测器，可以捕获地球表面发出的微波辐射。
The satellite carries a passive radiometer that captures the microwave radiation emanating from the Earth's surface.
X射线第一次被观察和记录是在1895年，当时德国科学家威尔姆·康拉德·伦琴在使用真空管做实验时意外发现了X射线。与光线和无线电波一样，X射线也是一种电磁辐射。
X-rayswere first observed and documented in 1895 by Wilhelm Conrad Roentgen, a Germanscientist who found them quite by accident when experimenting with vacuumtubes.
但核辐射不同于普通的无线电波，它对人类以及其他生物不是无害的。
But unlike common radio waves, nuclear radiation is not harmless to human beings and other living things.
但在黑洞，一系列活动创造高能量辐射-包括无线电波和X射线-即不流送入太空。
But around black holes, a flurry of activity creates high-energy radiation - including radio waves and X-rays - that does flow out into space.
各种辐射能，例如光，X射线以及无线电波，彼此很不相同。
Different kinds of radiant energy, such as light, X rays, and radio waves, seem very different from each other.
用来传送数据的电磁能量可以是电子脉冲，也可以是无线电波或光线之类的辐射能量。
The electromagnetic energy employed to carry the data can be in the form of electric impulses or radiated energy in the form of either radio waves or light rays.
通信、广播、电视、雷达、导航等无线电技术设备中，都需要有无线电波的辐射和接收，进而离不开天线设备。
In modern radio technology components such as communication, broadcast, television and radar system, the radiation and receiving of the radio waves are inevitably, then antenna is needed.
