draw the terminology associated with laws of reflection and state the laws of reflection
Answers
Explanation:
Laws of reflection - law
Laws of reflection states that: The incident ray, the reflected ray and the normal at the point of incidence all lie in the same plane. Angle of incidence is equal to the angle of reflection.
REFLECTION - DEFINITION
Reflection: Bouncing back of a light ray after hitting a surface.Incident ray: The light ray which strikes the surface.Reflected ray: The light ray which returns from the surface after reflection.Normal: An imaginary line perpendicular to the surface passing from the point of contact.Angle of incidencei: Angle between the incident ray and the normalAngle of reflection r: Angle between the reflected ray and the normal.
LAWS OF REFLECTION -
- The incident ray, the reflected ray and the normal at the point of incidence all lie in the same plane.
- Angle of incidence is equal to the angle of reflection.
VERIFICATION OF LAWS OF REFLECTION - EXAMPLE
Laws of verification can be experimentally verified by drawing the trace of a ray of light before and after reflection. This can be done by passing light through a small hole in a dark room or using two thin objects (like needles/pins) to trace a straight line and observe its reflection.
