LOST characteristics for an object past 2F of a converging lens
L =between 2F and F O= Inverted S = smaller T= real
LOST characteristics for an object on 2F of a converging lens
L= same or at 2F o= inverted s= same T= real
LOST characteristics for an object between 2F and F of a converging lens
L= beyond 2F o=inverted s= larger t= real
LOST characteristics for an object on F of a converging lens
No Image Formed
LOST characteristics for an object in front of F of a converging lens
L= Behind the lens O= Upright S= larger T= virtual
LOST characteristics for a diverging lens
L= Behind the lens O= Upright S= Smaller T= virtual
Similarities and differences between lenses and mirrors
Similarities -can make images that are real or virtual, upright or inverted and bigger or smaller -SALT can be used to describe changes for both Differences -in lenses light bends (refracts) in mirrors it bounces
when receiving questions about how deep an object would appear what is the 2 words that need to be stated
Apparent Depth
convex is like which type of lense
converging
concave is like which type of lense
diverging
In thin lense equations how do you know if D0 is negative or postive
ALWAYS POSITIVE
In thin lense equations how do you know if Di is negative or postive
real= postive virtual= negative
In thin lense equations how do you know if F is negative or postive
converging= positive diverging= negative
when is Hi negative for thin lense equations
when it’s an inverted image
