Tại sao người ta gọi là "KHÔNG GIAN" ????

Why are we called a "SPACE"????

wow ... 911 giỏi wa ......


Vậy tại sao người ta cho rằng SKY IS BLUE ?? Why is Sky is blue ? tại sao không phải la mau khác ... mà nhất đinh là BLUE ??? :P :D :huh: :o

The blue in the sky we see is scattered blue light !

Blue light gets scattered (spread) around much more than all the other colors from the sun, causing the sky to appear blue. (The oxygen and nitrogen molecules cause the sky to appear blue because of scattering.)

Đố lại nè :


<span style=\'color:blue\'>.

1. Why are clouds white?

True or False ? Giải nghĩa nhen ;)

2. The shorther the wavelength of the color, the more that color gets scattered by the atmosphere.

3. Sunsets are red because all other light is scattered away.



Fill in blank :

4. Light is made up of _________ waves.

5. ________ has the shortest wavelength of all colors.

6. ________ has the longest wavelength of all colors.

1. Why are clouds white?
Water and ice in clouds scatter all color wavelengths by the same amount
True or False ? Giải nghĩa nhen� ;)

2.� The shorther the wavelength of the color, the more that color gets scattered by the atmosphere.

3.� Sunsets are red because all other light is scattered away. FALSE
all the colors are scattered around so much by all this atmosphere that only red, orange and yellow light remains visiblẹ

4. Light is made up of _________ waves.
all the colours
5. ________ has the shortest wavelength of all colors.

6. ________ has the longest wavelength of all colors.

1) Clouds are made of water droplets, which are bigger than the wavelength of red light. This means they can scatter red and blue light equally well, and clouds will be the same color as the white sunlight shining on them.

2)True.. If the light has a shorter wavelength than the particle it hits, it cannot get around the particle and will be scattered.

3)Sunsets are red because all other light is scattered away.. False, other colors dont just scattered away, íts just becuz red is the longest wavelength of light, so we can easily see it

4)light waves

5)blue ....

6)red.....

I can believe it .. you are so good baby 911 ;)

1, 2, ,6 đúng, clappppppppppppp Asiangirl911,
3, 4 and 5 sai , trả lời lại nha kưng ;)

Câu 3 là True >>> sunsets are red because all other light is scattered away.
- Sunsets are red because all the other colors are scattered around (and diluted) so much that only red, orange and yellow light remains visible.


4. Light is made up of _________ waves. << fill in blank chữ "light" hong đúng .

5. ________ has the shortest wavelength of all colors. << " blue" hong đúng .
