Moment of Inertia Definition
The moment of inertia ‘I’ of a body is a measure of its ability to resist change in its rotational state of motion.
Uniform Rod About One End
Moment of inertia of a uniform rod about one end of uniform rod and perpendicular to its length is ML²/3.
Uniform Rod About Perpendicular Bisector
Moment of inertia of a uniform rod about perpendicular bisector is ML²/12.
Uniform Ring About Natural Axis
Moment of inertia of uniform ring about its natural axis is MR².
Uniform Disc About Natural Axis
Moment of inertia of uniform disc about its natural axis is MR²/2.
Hollow Cylinder About Natural Axis
Moment of inertia of hollow cylinder about its natural axis is MR².
Solid Sphere About Natural Axis
Moment of inertia of solid sphere about its natural axis is 2MR²/5.
Refraction of Light
The bending of the ray of light at the interface when it travels from one medium to another is called refraction of light.
Medium Definition
A transparent substance in which light travels is known as a medium.
Speed of Light Values
The speed of light in air is 3 × 10⁸ m/s whereas that in glass is 2 × 10⁸ m/s.
Optically Rarer Medium
A medium in which the speed of light is more is known as an optically rarer medium.
Optically Denser Medium
A medium in which the speed of light is less is known as an optically denser medium.
Bending Towards Normal
When a ray of light travels from a rarer medium to a denser medium it bends towards the normal.
Bending Away From Normal
When a ray of light travels from a denser medium to a rarer medium it bends away from the normal.
