Question

1. what is created when a single laser beam is split into two different beams by a mirror?

○ holograph
○ hologram
○ autograph
○ monograph

Explanation:

To solve this, we analyze each option:

• "Holograph" is the process/device related to creating holograms, not the result of splitting a laser beam.
• "Hologram" is created using the interference of laser beams (including splitting a single beam into two to create interference patterns).
• "Autograph" is a person's own signature, irrelevant here.
• "Monograph" is a detailed written study on a single subject, not related to laser beams.

So the correct option is the one related to the laser beam splitting for interference, which is the hologram - creating process's result from split laser beams.

Answer:

B. hologram (assuming the options are labeled with B for "hologram" as per typical multiple - choice formatting; if the original options had labels like A, B, C, D with "hologram" as one, the answer would be the option with "hologram", e.g., if "hologram" is option B, then B. hologram)
