Answer:
Spatial interference describes the correlation between waves at different points in space.
The two example of spatial interference are as following:
- alphanumeric characters can be easily identified in isolation but difficult to be identified when these characters are surrounded by optotypes because visual acuity will be reduced by crowded conditions that limit resolution at several stages of visual processing.
- Birds are able to identify visual target slowly that are presented at the top than to that same visual target presented at the bottom.
Hence, different waves in a space correlate result into Spatial interference.
