it is called a DIFFRACTION
refraction :)
Refraction
The speed of a mechanical wave depends on the mechanical properties of the medium. When the mechanical properties of the medium change, the speed of the mechanical wave changes as a result. The speed of an electromagnetic wave depends on the electrical properties of the medium. When the electrical properties of the medium change, the speed of the electromagnetic wave changes as a result.
Yes, WAVE motion is slowed by the higher Density of the Medium.
Refraction.
The change in direction is called refraction.
The speed of a wave is a property of the medium, changing the speed would need a change in the medium itself. If the medium doesn't change as a wave moves, the wave speed is steady. Formula: Speed = distance divided by time

because the density of the medium changes with temprature

The speed of light changes when it goes from one medium to another one with a different index of refraction. The angle of incidence doesn't influence the change in speed.
Refraction phenomenon Typically, the change in wave speed in the material causes the change in direction.
diffraction
Then, if they don't arrive from the direction perpendicular to the interface, they are refracted.
