Study Notes
Light is a form of energy that makes objects visible and is responsible for the sense of sight. It is emitted from a source such as the Sun and is usually visible to the human eye as visible light. In this article, we will be focusing on the subtopics of reflection of light, reflection of light, and its properties, shadows, and its formation.
Reflection of Light: Reflection occurs when a ray of light falls on a surface and bounces back. This phenomenon is known as reflection. The laws of reflection states that when a ray of light reflects off a surface, the angle of incidence is equal to the angle of reflection. This property of light is responsible for the formation of shadows and pinhole image.
Reflection of Light: Reflection occurs mainly on mirror surfaces as incident light gets reflected when it falls on a surface with shiny and glossy properties. The angle of incidence is the angle between the incident ray and the normal, and the angle of reflection is the angle between the reflected ray and the normal. The normal is an imaginary line that is perpendicular to the reflecting surface.
Reflection of Light: When an opaque object is placed between a point light source and a screen, the shadow formed is (i) Uniformly dark (ii) Sharp at the edges and (iii) Of the same shape as the object. When an opaque object, larger than the light source, is placed between the light source and the screen, two patches are formed; umbra and penumbra. The umbra is the dark shadow formed by the object, and the penumbra is the light shadow formed by the object.
