Question

explain law of reflection and retraction​

Answer 1

Answer:

Laws of Reflection and Refraction

• There are three laws which govern Reflection and Refraction. These can be very easily derived from geometry.
• They are:Angle of Incident Ray with Normal(i) EQUALS Reflected Ray with Normal(r).(i=r)
• Popularly known as SNELL'S LAW it is n1*sin i=n2*sin e where i is same as above,e is angle of refracted beam with normal.
• The INCIDENT ray,REFLECTED ray, REFRACTED ray and the NORMAL at the point of incidence all lie in the same plane.The plane is referred as plane of incidence.

Answer 2

Answer:

HII MATE

Once the ray of light strikes a surface of an object, it forms an angle of incidence and the angle of reflection.

The Angle of Incidence: The angle which the incident ray forms with the normal line at the point of incidence.

The Angle of Reflection: The angle which the reflected ray forms with the normal at the point where the reflected ray bounces back.
