View from a periscope Crossword Clue

 The answer to the crossword clue "View from a periscope" is INVERTED.

A periscope is an optical instrument that allows a person to see above or below the surface of water without having to expose themselves. It works by reflecting light through a series of mirrors or prisms. The view from a periscope is inverted because the mirrors or prisms reverse the image.

The clue "inverted" is a reference to the fact that the view from a periscope is upside down. This is because the mirrors or prisms in a periscope reflect the image twice, which reverses it.
