Also, when the same water passes through an object of different bulk, such as seawater and fresh water, it still bends and bounces back. This is the phenomenon of refraction of light.
In the case of the phenomenon called "shinkirou," light passes through a place where warm air and cold air meet and do not mix, causing the light to be bent.
This bending of light causes distant objects that are normally invisible to the naked eye to appear to float in the air. Of course, since various conditions must be met in order for the shinkiro to be visible, it is not always possible to see it.
In Japan, shinkirou can sometimes be seen on the Uozu Coast of Toyama Prefecture.
