Sound And Light Flashcards
Plane mirror
A mirror with a flat reflective surface
Specular reflection
A exact reflection image
Refraction
The bending of light waves when they slow down when they go through a different medium example through glass.
Diffuse scattering
Reflection from a rough surface
Law of reflection
The law of reflection says that the incident ray is always equal to the ray of reflection.
Reflected ray
The reflected ray is the ray of light that is reflected from the mirror , it is always equal to the ray of incidence.
Refracted ray
The refracted ray is the ray that is refracted.
Angle of refraction
The angle made by the refracted ray
Medium
Any substance eg: air, glass ect
Cornea
The cornea is the piece of skin protecting the pupil and the lens.
Lens
The lens is the part in your eye which is see through, the image is upside down but your brain flips it round.
Retina
The part in your eye which sees colour
Convex lens
A lens that converges the image, you use it when you are long sited
Concave lens
A lens that diverges the image, you use it when you are short sited
Dispesion
The dispersal ( splitting ) of white light into colours of the spectrum. This is due to the reflection in which each colour travels at different speeds.
