A gun of mass 'M' fires a bullet of mass 'm' with a horizontal velocity 'v'. The gun is fitted with a plane mirror facing towards the receding bullet. Find the velocity relative to its image just after the gun is fired.

Reflection of light is the phenomenon where light bounces off a surface and changes direction. This can happen with all types of light, including visible light, infrared, and ultraviolet.
The law of reflection states that the angle of incidence (the angle at which the light hits the surface) is equal to the angle of reflection (the angle at which the light bounces off the surface). This law applies to all types of light and all types of surfaces.
The angle of incidence and the angle of reflection are always equal, regardless of the type of surface. This means that if the angle of incidence is increased, the angle of reflection will also increase.
Regular reflection occurs when light bounces off a smooth and flat surface, such as a mirror. The light rays remain parallel and the image is clear. Diffuse reflection occurs when light bounces off a rough surface, such as paper or fabric. The light scatters in different directions, resulting in a blurred or diffused image.
Reflection of light is used in various applications, such as in mirrors, lenses, and reflective surfaces. It is also used in optical devices such as telescopes, microscopes, and cameras. In addition, reflection is used in many industries, including telecommunications, automotive, and construction.
