light

Question 1

what is light made out of?

Answer 1

Photons

Question 2

what does transparent material do?

Answer 2

they transmit light through them

Question 3

what does translucent material do?

Answer 3

transmit some light through them but not all

Question 4

what does opaque material do?

Answer 4

absorb light or reflects light.

Question 5

how is a shadow made?

Answer 5

light source is blocked by an object, casting a shadow behind the object.

Question 6

how is the size of a shadow determined?

Answer 6

depends of the distance from the light source.

Question 7

what is it called when light bounces off something?

Answer 7

reflected

Question 8

what happens when light goes through dense material

Answer 8

it will bend and seem to be farther away than it really is.

Question 9

what are mirages?

Answer 9

they are formed by the refraction of light as it passes from less dense hot air to make cooler less dense air

Question 10

why do you see fake pools of water on the road during a hot day?

Answer 10

the light bends as it passes through the air making it look like there is reflective water on the ground.

Question 11

whats a mirror?

Answer 11

they are polished objects that reflect light

Question 12

whats a plane mirror?

Answer 12

a flat mirror that makes the image look like its behind the mirror itself

Question 13

is the image of a plane mirror inverted?

Answer 13

yeah

Question 14

what happens to a plane mirrors image if you move away and walk close to it?

Answer 14

the image moves with you and never changes.

Question 15

whats a concave mirror?

Answer 15

its curved inwards like a cave hence the name.

Question 16

what do distant objects look like on a concave?

Answer 16

they seem small and inverted

Question 17

what happens when you approach the concave closer?

Answer 17

object still gets inverted but also gets bigger

Question 18

if a object is between the focal point on the concave, what happens?

Answer 18

become large and up right

Question 19

whats a convex mirror?

Answer 19

curves outward.

Question 20

how do images look on a convex mirror?

Answer 20

behind the mirror and smaller than they are. you can also see more of a room compared to a plane mirror

Question 21

what are the rays called that split from a convex mirror?

Answer 21

lingering rays

Question 22

how does light bend through glass?

Answer 22

bends through glass then bends again as it goes through the air.

Question 23

what are lenses?

Answer 23

a lens is a curved piece of transparent material that bends light in a controlled way. they can cause light to converge or diverge as light passes.

Question 24

explain a concave lens

Answer 24

thinner in the middle, they diverge the light rays, and image is formed up right and smaller than actual object.

Question 25

explain a convex lens

Answer 25

thicker in the middle, light rays converge, image form depends on how you angle it.

Question 26

what does diverge mean?

Answer 26

spread out

Question 27

what does converge mean?

Answer 27

come together
