In the case of fog or blizzard conditions the observer should read the scale where the beam disappears.

Suddenly the relay sounded again; the beam of radiance disappeared as quickly as it had come.

"If those beams are disappearing, where are they going?"

The red beam disappeared and the conveyor belt started to move.

A hot beam flashed from the muzzle of the gun and the menacing figure disappeared abruptly.

The beam disappeared, but a patch of the ceiling next to the hole continued to glow.

What's more, the beams raking the capital disappeared in an explosion of blue-white energy.

The beam of the storm lantern disappeared ahead of him, and now he stepped out to catch up.

Two brighter beams struck the door and also disappeared into its surface.

Solid beams mitered the air, rose through the plumes, and disappeared beyond sight.
