Helpful? Today we are going to learn about some simple physics by doing simple and easy science activity i.e. Refraction of light is an important aspect in the physics of lenses, especially with regards to how a single lens or multi-lens system is designed and constructed. Q2. College of Staten Island CUNY. Reflection is a familiar concept. ABSTRACT When light is reflected the direction it is facing bounces off a reflected surfaces to a different direction or angle, while refraction is the change in the direction of light as it passes a medium. CH. Bending happens whenever light changes medium in which it’s traveling. Objects must have one important property to be seen: they must. Preschool. Refraction is the bending of light. Irregular reflection: Irregular reflection also termed as diffuse reflection, which occurs when the beam of light falls on the rough surface and reflects light in various directions. The law of reflection states that, on reflection from a smooth surface, the angle of the reflected ray is equal to the angle of the incident ray. Prep Time: 30 minutes.
