The ________ at the point of incidence is different for different rays.
New cards
2
Concave mirrors
________ are used in certain types of astronomical telescopes called reflecting telescopes.
New cards
3
Specular Reflection
________: the angle of incidence is equal to the angle of reflection.
New cards
4
individual incident
The reflected light from each ________ ray follows the law of reflection.
New cards
5
Parallel rays of light
________ strike the convex mirror and are reflected outwards.
New cards
6
Angle of incidence
the angle at which light hits a reflecting surface
New cards
7
Angle of reflection
the angle at which light bounces off a reflecting surface
New cards
8
Specular Reflection
the angle of incidence is equal to the angle of reflection
New cards
9
Diffuse reflection of light
results in light rays reflected at many angles, rather than at just one angle as in the case of specular reflection; angle of incidence is not equal to the angle of reflection
New cards
10
Reflection of light on a concave mirror
when parallel light rays hit a concave mirror they reflect inwards towards a focal point
New cards
11
Reflection of light on a convex mirror
when parallel light rays hit a convex mirror they reflect outwards and travel directly away from an imaginary focal point
New cards
12
In diffuse reflection the normal line at the point of incidence
is different for different rays
New cards
13
Water is a
reflective surface.
New cards
14
When the water in a lake or sea is very still,
the reflection of the landscape is perfect, because the reflecting surface is very flat.
