In Class 10 Physics (Light - Reflection and Refraction), understanding the anatomy of a spherical mirror is essential. The Centre of Curvature is one of these fundamental points.
Definition: Centre of the sphere of which the mirror forms a part.
Symbol: C.
Concave Mirror: C is in front.
Convex Mirror: C is behind.
Radius of Curvature (R) = Distance from Pole to C.
A spherical mirror (concave or convex) is essentially a cut-out part of a large hollow glass sphere.
The Centre of Curvature (C) of a spherical mirror is the centre of the hollow glass sphere of which the mirror is a part.
The centre of curvature is the centre of the imaginary hollow glass sphere of which the spherical mirror is a part.
For a convex mirror, the centre of curvature lies behind the reflecting surface.
What is Watt-Hour Efficiency of a Battery?
Learn about the Watt-Hour Efficiency of a lead-acid battery. Understand the definition, formula, and the difference between Ampere-hour and Watt-hour efficiency.
Wavelength of Sound Waves in Hydrogen Gas
Speed of sound in hydrogen at 0°C ≈ 1270 m/s. Wavelength λ = v/f. For 1000 Hz: λ ≈ 1.27 m. Hydrogen has the highest speed of sound among common gases.
