Flashcards

Light's Wave Nature

Light travels as a transverse wave, not needing a material to move through.

Light's Particle Nature

Light consists of tiny packets of energy called photons.

Dual Nature of Light

Light acts like both waves and particles in different situations.

Law of Reflection (Angle)

The angle at which light bounces off a surface equals the angle at which it hits.

Study Notes

Light and its Nature

Light is a form of energy that allows us to see objects.
Objects reflect light that falls on them.
Light does not require a medium to travel.
Light is a transverse wave.
Wave nature of light is explained by Huygen's theory.
The particle nature of light is explained by the Corpuscular theory.
Quantum theory treats light as packets or bundles of energy (photons).
Light exhibits both wave-like and particle-like properties.

Laws of Reflection

Light reflects according to the laws of reflection.
The angle of incidence equals the angle of reflection.
The incident ray, the reflected ray, and the normal all lie in the same plane.
