Refractive index of glass (ng) = \\(Speed of light in vacuum \\over speed of light in the glass.\\)
A plane mirror is a mirror with a flat (planar) reflective surface. Lateral inversion happens in plane mirror.
A plane mirror is a mirror with a flat (planar) reflective surface.
A plane mirror is a mirror with a flat (planar) reflective surface. For light rays striking a plane mirror, the angle of reflection equals the angle of incidence.
The virtual image occurs where rays only appear to diverge. Concave mirror forms virtual image when object is between pole and focus.
A plane mirror is a mirror with a flat (planar) reflective surface. For light rays striking a plane mirror, the angle of reflection equals the angle of incidence.
An order of magnitude is an approximation of the logarithm of a value relative to some contextually understood reference value, usually, 10, interpreted as the base of the logarithm and the representative of values of magnitude one.
A plane mirror is a mirror with a flat (planar) reflective surface.
A real image occurs where rays converge, whereas a virtual image occurs where rays only appear to diverge.
The refractive index of air is about 1.0003, and from this equation we can find that the speed of visible light in air is about 90 km/s slower than c.
