N.C.E.R.T. Textual Questions-UNIT-5 Ques. 5.01–N.C.E.R.T. Textual Questions-UNIT-5 Figure 5.01 shows a capacitor made of two circular plates, each radius is 12 cm and separated by 5.0 cm. The capacitor is being charged by an external source, (not shown in the…
Spherical Refracting Surfaces-12 Spherical Refracting Surfaces are the spherical refracting surfaces that form the part of a sphere of a refracting medium. Types of Spherical Refracting surfaces-12 The Spherical Refracting Surfaces-12 are categorized into two types. Convex Spherical Refracting Surface-12…
Lenses-12 A lens is a piece of transparent material bounded by two opposite regular spherical surfaces, either both curved or one curved, and the other plane. Such type configuration is used either singly or combined in an optical instrument for…
images formed by lenses The images formed by lenses-12 when the two or more light rays from different parts of an object after refraction through the lenses actually converge at a point or appear to do so. image formed by…
Total Internal Reflection When a light ray is incident at interface backed by a rarer medium at an angle greater than the critical angle, then the ray will be reflected in to the same medium, which is called Total internal…
refraction of light-12 It is the deviation of the light ray from its original path when it goes from one medium to another medium of different densities. It is evident from the experimental observations that the light ray, in a…
What is Reflection of Light at curved surfaces? The curved reflecting surfaces are the mirrors called concave or convex types. Spherical Mirrors A spherical mirror is portion of a reflecting surface which forms a part of the sphere. When we…
Mirror Formula -12 It is the relation between the distance of the object(u), the distance of the image (v), and the focal length of the spherical mirror. The mirror formula can be derived by making use of different sign conventions….
Reflection of Light-12 What is Reflection of Light-12 It is the re-bounce of light from a smooth surface after striking it is known as the reflection of light When a light ray is allowed to incident on a surface, it…
