Light emitted in this environment will have a certain frequency, which is related to the time scale (or the gravity strength) of the environment.

在那样环境下所发射的光会具有一定的频率，这个频率是与环境的时间标度(或引力强度)有关。

When that light travels to a new environment, say to a telescope on Earth, where there is comparatively lower gravity, and time moves more slowly, the light's frequency will decrease.

当光运行而到达一个新的环境时，譬如到达了地球上的某个望远镜，由于地球上只有较小的引力，时间的流逝就会变慢，由此光的频率就会降低。

youdao

Gravity waves have a frequency of about once every 30 seconds.

重力波的频率为每30秒一次。
