That usually refers to a line that is perpendicular (at right angles, i.e., at a 90° angle) to something else - for example, to the plane of a mirror.

What is meant by the normal in a ray diagram?

a normal is the middle line from where angle of incidence and angle of reflection are same


What branch of physics that study about light?

The branch of physics that studies light is called optics. Optics involves the behavior and properties of light, including its interactions with materials and its manipulation through lenses, mirrors, and other optical components. This field explores phenomena such as reflection, refraction, diffraction, and polarization of light.


What is the angle that the incoming wave makes with the normal equals the angle that the outgoing wave makes with the normal?

This situation involves the law of reflection, which states that the angle of incidence (incoming wave) is equal to the angle of reflection (outgoing wave) with respect to the normal line perpendicular to the surface. This means that the incident angle = reflected angle with respect to the normal line.


Does meaning of normal change when representing refraction?

In the context of refraction, "normal" refers to an imaginary line perpendicular to the surface at the point where the light ray hits. It is used as a reference point to determine angles of incidence and refraction. The concept of "normal" remains the same in this context as it is used in optics to describe the behavior of light waves.


What is the line perpendicular surface at the point is incidence?

The line perpendicular to a surface at the point of incidence is known as the normal line. It represents the direction that is perpendicular to the surface at that specific point. This normal line is used in optics to determine the angle of incidence and reflection for light rays interacting with the surface.

What dose aberration mean?

Aberration refers to a deviation from what is normal, expected, or acceptable. In optics, aberration is a distortion in the image formed by a lens or mirror. In behavior or thinking, aberration can refer to a departure from usual patterns or norms.

What is the probability of having a normal child?

The probability is zero! There is no such thing as "normal". Every child (and adult) has some unique characteristics and that makes them not normal - in that respect.
