What is the change in the direction of light by a mirror called ______...
- The process through which light rays falling on the surface of an object are sent back is called a reflection of light.
- Thus, when light falls on the surface of an object it sends back the light.
- Reflection of light occurs when the waves encounter a surface or other boundary that does not absorb the energy of the radiation and bounces the waves away from the surface.

What is the change in the direction of light by a mirror called ______...
The change in direction of light by a mirror is called reflection. ... When a beam of light rays falls on the surface of a concave lens, the concave lens tends to bend the rays outward. Hence, all the rays diverge away from the lens. Therefore, a concave lens is also called a diverging lens.

What is the change in the direction of light by a mirror called ______...
Understanding Reflection of Light
The change in the direction of light when it strikes a mirror is known as reflection. Here’s a detailed explanation:
Definition of Reflection
- Reflection occurs when light rays bounce off a surface.
- In the case of a mirror, a highly polished surface ensures that the majority of light is reflected rather than absorbed.
Law of Reflection
- The angle of incidence (the angle at which incoming light hits the surface) is equal to the angle of reflection (the angle at which light leaves the surface).
- This relationship can be expressed as: Angle of Incidence = Angle of Reflection.
Types of Reflection
- Regular Reflection: Occurs on smooth surfaces like mirrors, producing clear and defined images.
- Diffused Reflection: Happens on rough surfaces, scattering light in various directions, which does not produce a clear image.
Applications of Reflection
- Mirrors are widely used in everyday life for personal grooming, safety devices (like rear-view mirrors), and optical instruments (like telescopes).
- Understanding reflection is crucial in designing optical devices and enhancing visual technologies.
Conclusion
- In summary, the correct answer to the question about the change in the direction of light by a mirror is "reflection of light."
- This phenomenon is fundamental to optics and is essential for various practical applications in our daily lives.
