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.
