There are two main laws that govern the reflection of light:
The law of incidence: This law states that the angle of incidence is equal to the angle of reflection. In other words, the angle at which light strikes a surface is equal to the angle at which it reflects off the surface.
The law of reflection: This law states that the incident ray, the reflected ray, and the normal to the surface at the point of incidence all lie in the same plane.
Practicing problems involving the calculation of angles of reflection
Exploring real-world examples of reflection, such as the behavior of light in a kaleidoscope or in a periscope
It's also essential to understand the practical applications of reflection in everyday life, from the design of optical instruments to the functioning of reflective materials in safety gear and road signs.
By mastering the principles of reflection of light, you'll develop a deeper understanding of how light behaves and how it can be manipulated in various applications.
Identify and analyze forces responsible for changes in rotational motion and develop an understanding of the effect of rotational inertia on the motion of a rotating object (e.g., merry-go-round, spinning toy, spinning figure skater, stellar collapse [supernova], rapidly spinning pulsar).
