NCERT Solutions for Class 12 Physics Chapter 9: Points to Remember

Some of the important points to remember from this chapter are as follows:

The phenomenon of changing the path of light without changing the medium is known as reflection.
Therefore, a reflection of light is the return of light in the same medium from which it came after striking a surface.
Total internal reflection occurs when light is completely reflected as it travels from a denser medium to a rarer medium.
The focal length of the eye lens can be adjusted so that the image is always formed on the retina by the eye’s ability known as accommodation.
Also, the incident, reflected, and normal rays exist in the same plane.
Moreover, distances measured parallel to the incident light are positive; while distances measured perpendicular to the incident light are negative.
The focal length (f) of a concave mirror is negative, while it is positive for a convex mirror.
The splitting of light into its constituent colours is known as dispersion.
Also, the medium’s refractive index is affected by the frequency of the light.
