Introduction to Light – Reflection & Refraction
In Class 10 Science chapter 10 Light, the phenomena of reflection and refraction
of light using the straight-line propagation of light are taught to students.
Furthermore, optical phenomena in nature are examined. The reflection of light
by spherical mirrors is discussed in the chapter so that their applications are
studied in real-life situation
Light: Definition
Light is a form of energy that enables us to see things. Light starts from a source
and bounces off objects which are perceived by our eyes and our brain processes
this signal, which eventually enables us to see. Maxwell predicted that magnetic
and electric fields travel in the form of waves and these waves move at the speed
of light. This led Maxwell to predict that light itself was carried by electromagnetic
waves which means that light is a form of electromagnetic radiation .
Nature of Light
● Ray, e.g. reflection
● Wave, e.g. interference and diffraction
● Particle, e.g. photoelectric effect
