Refraction of light by spherical lenses is an essential concept in optics for Class 10 NCERT. Spherical lenses are transparent materials with at least one curved surface that cause light rays to bend or refract. They are primarily categorized into two types: Basic Terminology Refraction in Convex Lenses Convex lenses are thicker at the center …
Reflection of light by curved surfaces, particularly mirrors, is an important concept in optics. For Class 10 NCERT, it’s essential to understand how light interacts with concave and convex mirrors. Here’s a detailed explanation: Curved Mirrors Curved mirrors can be of two types: Basic Terms Reflection in Concave Mirrors For concave mirrors, the behavior of …

In the context of Class 10th ICSE (Indian Certificate of Secondary Education) Board, the concept of turning forces refers to the principles of rotational equilibrium and the factors affecting the turning or rotational motion of an object. It’s also commonly known as the concept of moments or torque. Understanding turning forces is essential not only …
Series Circuit: In a series circuit, resistances add up. The total resistance (RtotalRtotal) is the sum of individual resistances. Rtotal=R1+R2+R3+… Example: Suppose you have three resistors with resistances R1=5 ΩR1=5Ω, R2=3 ΩR2=3Ω, and R3=2 ΩR3=2Ω connected in series. The total resistance (RtotalRtotal) would be: Rtotal=5 Ω+3 Ω+2 Ω=10 Ω Parallel Circuit: In a parallel circuit, the reciprocal of the total resistance (Rtotal−1Rtotal−1) …

Projectile motion refers to the motion of an object that is thrown or projected into the air and is subject to the force of gravity. The key characteristic of projectile motion is that the object follows a curved path, known as a trajectory, rather than a straight line. This type of motion is a result …
Reflection of light refers to the process by which light waves bounce off a surface, changing direction without being absorbed. When light strikes a surface, it can be absorbed, transmitted, or reflected. Reflection occurs when light waves hit a surface and are bounced back in a new direction. The angle at which the light hits …
