An optical SETI signal would most likely consist of
A) using mirrors to reflect light from the surface of a planet
B) using a giant disk to block out the light from the parent star
C) rapid, short bursts of intense laser light
D) a continuous beam of laser light

Question

Quizplus · Accepted Answer

Optical SETI signals are usually assumed to be in the form of rapid, short bursts of intense laser light, as they are more efficient and have a higher chance of being detected over long distances compared to a continuous beam of laser light. This short burst of light can contain information about the sender, which can be decoded by the receiver. The other choices, such as using mirrors or a giant disk, are not commonly used methods for transmitting signals in optical SETI.
