Light – Reflection and Refraction
Science Solutions from Chapter -1 - Light – Reflection and Refraction
This chapter describes the optical phenomena of the reflection and the refraction of light. It explains the laws of reflection and refraction. Moreover, it mentions practical applications of these phenomena and the types of spherical mirrors.
Practice Other Topics from Light – Reflection and Refraction
This topic discusses the phenomenon of reflection, where a ray of light falls on a surface and gets reflected. According to its law, the incident ray, the reflected ray and the normal lie in the same plane and the angle of incidence is equal to the angle of reflection.
This topic states that a spherical mirror has a curved reflecting surface and it is of two types. A convex mirror or diverging mirror has its reflecting surface bulging outwards. A concave mirror or converging mirror has its reflecting surface caving inwards.
This topic explains the refraction phenomenon, when a ray of light passes from one optical medium to another medium and deviates. Snell’s Law of Refraction states that the ratio of the sine of the angle of incidence to the sine of the angle of refraction is constant.
This topic describes the refraction through spherical lenses with the help of ray diagrams. We shall also learn the nature, position and the relative size of the image formed by a convex and concave lens for various positions of the objects.
