Optical phenomenon 7 Little Words

The crossword clue "Optical phenomenon" with the answer "PARALLAX" refers to a visual effect where the position or direction of an object appears to differ when viewed from different perspectives. This phenomenon occurs because of the change in the observer’s point of view, which causes the object to shift against a background of distant objects.

Parallax is commonly observed in various contexts, such as astronomy, where it helps in measuring the distances of celestial bodies, and in everyday experiences, like when viewing objects from different angles or depths.

The crossword clue "Optical phenomenon" with the answer "REFRACTION" refers to the change in direction of light as it passes from one medium to another with a different density.

When light travels through materials such as air, water, or glass, it bends due to the difference in speed caused by the varying optical densities of these materials.

The crossword clue "Optical phenomenon" with the answer "DISPERSION" refers to the process by which light is separated into its constituent colors when it passes through a medium, such as a prism.

Dispersion occurs because different colors of light have different wavelengths and, as a result, are bent by different amounts when they enter or exit the medium.

The crossword clue "Optical phenomenon" with the answer "INTERFERENCE" refers to the effect observed when two or more light waves overlap and combine, resulting in patterns of constructive and destructive interference.

This phenomenon occurs when light waves meet in such a way that their crests and troughs align to either amplify or cancel each other out.
