Physics - SALT characteristics for mirrors AND lenses

Question 1

Converging (convex) lens, object between 2F’ and F’

Answer 1

Smaller, inverted, between F and 2F and behind lens, real

Question 2

Converging lens: is F’ on the left or the right?

Answer 2

left

Question 3

Diverging lens: is F’ on the left or the right?

Answer 3

right

Question 4

Converging lens, object at 2F’

Answer 4

Same size, inverted, at 2F, real

Question 5

Converging, object beyond 2F’

Answer 5

smaller, inverted, between F and 2F, real

Question 6

Converging lens, object within F’

Answer 6

larger, upright, behind object, virtual

Question 7

What else can we call F’?

Answer 7

F prime, aka secondary principal focus

Question 8

Any diverging lens

Answer 8

Smaller, upright, in front of object (same side of lens), virtual

Question 9

Concave mirror

Question 10

concave/convex=converging diverging memory aid??

Answer 10

cave: diver (concave is diverging)

Question 11

C,F,V order memory aid?

Answer 11

if we start at the point furthest from the mirror, it is in alphabetical order

Question 12

Concave mirror, object beyond C

Answer 12

smaller, inverted, same side of mirror between C and F, real

Question 13

Concave mirror, between C and F

Answer 13

larger, inverted, Beyond C, same side, real

Question 14

concave mirror, between F and V

Answer 14

larger, upright, behind mirror, virtual

Question 15

concave mirror, at C

Answer 15

same size, inverted, at C, real (to remember: the SEA/C: looks like a reflection in the water)

Question 16

Concave mirror, at F

Answer 16

no image formed because all rays are parallel

Question 17

Any convex mirror

Answer 17

smaller, upright, behind mirror between F and V, virtual

Question 18

curved mirrors: are C,F, V inside or outside the spoon

Answer 18

ALWAYS inside. This means on the left side for concave and the right side for convex (also means same side as object for concave and opposite side for convex)
