Light Flashcards
Angle of incidence
The angle an incoming ray makes with the normal
Angle of reflection
The angle a reflection ray makes with the normal
Angle of refraction
The angle a refracted ray makes with the normal
Critical angle
The angle of incidence of light that produces an angle of refracted of 90 degrees
Concave(converging)mirror
A mirror that curves inwards
Convex (diverging) mirror
A mirror that bulges outwards
Diffuse reflection
W
Incident ray
Incoming ray
Lateral inversion
The sideway or left-to-right reversal of an image in a plane mirror
Law of reflection
The law stating that light is reflected at the same angle that is incident, or i=r
Normal
An imaginary line that is drawn at right angles to a surface that light is incident upon
Parallel rays of light
W
Plane mirror
A flat mirror
Reflected ray
Ray that bounces of
Refracted ray
W
Refraction
The bending of light as it passes from one substance to another substance
Refractive index
A measure of how easily light travels through a substance
Regular reflection
W
Total internal reflection
When light is completely reflected from the boundary of two substance; it occurs when the angle of incidence is greater than the critical angle
Virtual image
An image formed in which the rays of light do not actually meet, but only appear to meet at a point inside the mirror
