Ray Tracing For Sphereical Mirrors Flashcards
1
Q
Ray tracing rule 1
A
The ray is parallel to the axis which is reflected through the focal point
2
Q
Ray tracing rule 2
A
Rays passing through the focal point are reflected parallel to the axis
3
Q
Ray tracing rule 3
A
Rays passing through the centre of curvature are reflected back on themselves
4
Q
Where is the image produced on a spherical diagram
A
Where the rays (3/2) interact
5
Q
n1 sini= n2 sinr
A
n1 =refraction of medium l
n2 = refraction of medium 2
i = angle of incidence
r = angle of refraction
6
Q
Where is the centre of curvature located on a convex reflecting surface
A
Located behind the reflecting surface
7
Q
Where is the centre of curvature located for concave reflecting surface
A
Infront of the reflecting surface
8
Q
What is the focal distance
A
It’s half the distance of c and p.
