Answer 1

i got this

Answer 2

i think

Answer 3

I believe it is B

Answer 4

Because all the other objects, diamond, prism, and spoon, refract light-waves as they hit or pass through the object

Answer 5

Are you absolutely positive?

Answer 6

yea its b

Answer 7

i was gonna say that

Answer 8

Wait, is the fourth picture about the tree? Or the snow? Because I believe snow refracts light

Answer 9

no not retricemuch

Answer 10

OK. Thanks guys.

Answer 11

its D

Answer 12

And this picture is water. Not a tree or snow.

Answer 13

yea its d cause the snows crystals reflect light

Answer 14

D. is not snow, it is two spoons.

Answer 15

D D D D D!!!
MORE REFLECTION ..LESS TRANSMITTED!..lol

Answer 16

Okay... I am going with D.

Answer 17

d

Answer 18

lets all give each other medals

Answer 19

Thank you to all! I have three more questions... Can you help/check those too?

Answer 20

I'll try and help ^_^

Answer 21

refraction occurs when the surfaces are semipermeable to light,
With the spoons the light can only be reflected because the light cannot pass through the spoon so there is no chance for refraction which occurs due to the minimization of time taken to get from point A to B

Answer 22

Thank you for your explanation! Very helpful. :)

Answer 23

: >

Answer 24

I can tell you more if you are interested

Answer 25

Any information is accepted. :)

Answer 26

Well you see refraction is happening first and foremost because light travels at different speeds in different materials

Answer 27

So if there is a surface that light can pass through it will try to minimize the time it takes to complete its path

Answer 28

By the way, I posted the next question.
