Ray Tracing for Physics

How does a concave lens look like, is it diverging or converging?​

diverging

How does a concave mirror look like? converging, diverging?

converging

how does a convex mirror look like? converging or diverging?

diverging

How does a convex look like? converging or diverging?

converging

For convex lens follows all three rules

concave mirrors follow the 2 rules ., what are the 3 rules?

1. -in parallel, out through focal point

2.-in the focal point, out parallel

3. -in center of lens and out center of the lens

Concave Mirror (Converging)

-ray directions when the object is before c?

-describe the image?

-in parallel, out focal point

-going through f and hit lens, out parallel the same way

-image smaller

-inverted

-real

-image is between c & f

Concave Mirror (Converging)

-ray directions when the object equals c?

-describe the image?

-in parallel, out the focal point

-through the focal point and hit the mirror, reflected back parallel

-the image is where c is

-same size

-inverted

-real

concave mirror (Converging)

-ray directions when the object is after c?

-describe image?

-in parallel, out through focal point

-through focal point and hit the mirror, reflected back the same way

-image is before c

-magnified/larger

-inverted

-real

Concave mirror (converging)

-ray directions when the object is at f?

-describe image?

-in parallel hit the mirror, reflect out the same way

-hit mirror, reflect out the same way

-no image b/c the rays are parallel

concave mirror (converging)

-ray directions when the object if after f?

-describe the image?

-in parallel hit the mirror and reflect back the same way hitting f, the dotted lines go through the mirror

-in hitting the mirror and reflect back the same way, the dotted lines go through the mirror

-the image is behind the mirror

-erect-

magnified/bigger

-virtual

convex mirror (diverging)

-ray directions?

-describe image?

-in parallel reflect out the same way up, rooted line go to f

-hit the mirror, out the same way parallel, the dotted line parallel on the same side

-hits the mirror and hits 2f or c on the other side

-the image is between f and mirror(behind the mirror)

-erect

-diminished/smaller

-virtual

Convex lens (converging)

-ray directions when the object is before 2f?

-describe the image?

-in parallel, out through the f

-through the center of the lens

-through the f, out parallel

-image between f & 2f

-smaller

-inverted

-real

convex lens (converging)

-ray directions when the object is at 2f?

-describe the image?

-in parallel, out through f

-through the center of the lens

-through f, out parallel

-image will be at 2f at the other side

-same size

-inverted

-real

convex lens(converging)

-ray directions when the object is between 2f &f?

-describe image?

-in parallel, out through f

-through the center of the lens

-through f, out parallel

-the image is after 2f on the other side

-bigger

-inverted

-real

convex lens (converging)

-ray directions when the object is at f?

-describe image?

-in parallel, out through f

-ignore through f, out parallel

-parallel rays

-no image

concave lens (diverging)

-ray directions?

-describe image

-in parallel, out up

-hit mirror, out parallel, dotted lines hit f in the left (in front of the lens) parallel

-right through center

-the image between f and lens (in front of the lens)

All converging lenses have positive di

For diverging lenses di is negative

The do is always positive

For converging the, M, magnification? is negative
