1. An electromagnetic wave detection apparatus comprising:
a separation unit configured to separate and propagate incident electromagnetic waves in a plurality of directions;
a first detector configured to detect separated first electromagnetic waves; and
a second detector configured to detect second electromagnetic waves separated in a different direction than the first electromagnetic waves and to change an amplification factor of a detection signal in accordance with a detection result of the first detector,
wherein the first detector is configured to detect the first electromagnetic waves more frequently than a rate at which the second detector is configured to detect the second electromagnetic waves.
