Due to multiple reflection!
reflection
Reflection off of rough surfaces is called a perkokepuw.
Reflection of an object is the flip of that subject on a particular line, that is called line of reflection.

Multiple reflection is used for stethescope to hear the heartbeat of the patient.
The multiple reflection of a single sound wave is an echo.

Multiple reflection can be used to increase the path length of light within a system, allowing for improved sensitivity in applications such as optical sensing or interferometry. It can also be used to create optical cavities for lasers and resonators to enhance amplification or filtering of light. Additionally, multiple reflection is utilized in some optical devices like corner cubes and retroreflectors for redirecting light efficiently.
Examples of multiple reflections include a mirage in the desert, where light is reflected multiple times between layers of air at different temperatures, and a kaleidoscope, where light reflects off multiple mirrors to create intricate patterns. Another example is the double reflection seen in a water puddle, where light reflects off the surface of the water and then off the ground below.
The laws of reflection are based on the reflection of light from a smooth, flat surface. In the case of irregular reflection, where the surface is rough or uneven, the laws of reflection may not hold true as the angle of incidence may not be equal to the angle of reflection. Irregular reflection results in scattering of light in multiple directions.
Multiple reflection of sound can help doctors create detailed images of internal organs using techniques like ultrasound. Engineers use multiple reflection of sound to detect flaws in materials such as metal or concrete, allowing them to assess structural integrity without needing to physically inspect the entire surface.
No, in irregular reflection, the angle of reflection is not equal to the angle of incidence. Irregular reflection occurs when light rays hit a rough or uneven surface, causing them to reflect in multiple directions. In these cases, the law of reflection does not apply strictly.
In a kaleidoscope, multiple reflection occurs when light enters the tube and bounces off the internal mirrors multiple times. Each reflection creates a pattern by reflecting the colored objects placed at one end of the tube. This repeated reflection creates beautiful and intricate symmetrical patterns seen through the viewing hole at the other end of the kaleidoscope.
Multiple reflection of sound occurs when sound waves bounce multiple times between surfaces before reaching the receiver. This can create echoes and reverberation in an enclosed space, affecting the clarity and intensity of the sound. Multiple reflections can be controlled through sound absorption materials or strategic placement of sound-reflecting surfaces.
Seismic reflection
Multiple reflection by a plane mirror can be used in applications such as periscopes, kaleidoscopes, and in the design of laser cavities for amplifying light intensity. It can also be used in some optical illusions and art installations to create interesting visual effects.
