The U. S. has an alternating current frequency of 60 Hz. China has an alternating current frequency of 50 Hz. This means that the number of times voltage cycles in a minute in the U. S. is greater than the number of times voltage cycles in China.

A light ray travels inside a horizontal plate of glass, striking its upper surface at an angle of incidence of 50°. This ray is totally internally reflected at the glass-air boundary. A liquid is then poured on top of the glass.
