what type of lens forms real images

converging lens

(si positive, image is real)

New cards
2

what type of mirror forms real images

concave mirror

(si is positive, image is real)

New cards
3

what side of the mirror do real images form

on the same side as the object

New cards
4

what side of the mirror do virtual images form

the opposite side of the object

New cards
5

virtual images are always ___

virtual images are always upright and located behind the mirror

(positive M value) (negative si value)

New cards
6

real images are always ___

real images are alwasys inverted and located in front of the mirror 'cone

New cards
7

convex mirrors can only form ___ images, because ____

convex mirrors can only form virtual images, because f is negative and so is positive- the onyl way to satisfy the euqation is for si to then be negative. ( thus image is located on opposite side of mirror).

diverging lenses create ___ images

diverging lenses create virtual images

New cards
9

converging lenses are also called ___ lenses, because?

converging lenses are also called convex lenses because f is positive

however! converging lenses still always make real images. can

New cards
10

diverging lenses are also called ___ lenses, because?

diverging lenses are also called concave lenses because f is negative

however! diverging lenses still always make virtual images.

15

what is the difference between electric and gravitational fields?

Electric fields are caused by electric charges, while gravitational fields are caused by mass.

Electric fields attract or repel charges, while gravitational fields attract masses.

the relationship between the density of a gas and its temperature

As the temperature of a gas increases, its density decreases.

Explanation:

When the temperature of a gas increases, the gas molecules gain kinetic energy and move faster, spreading out more. This results in a decrease in density because the same amount of gas now occupies a larger volume due to increased molecular motion.
