What causes refraction when light travels from air into glass? What happens is thatlight slows downwhen it passes from the less dense air into the denser glass or water. This slowing down of the ray of light also causes the ray of light to change direction. It is the change in the spee...

Question: QUESTION 2When light travels from a faster medium, such as air, into a slower medium, such as glass, which of the following will happenThe wavelength will decreaseThe frequency will increaseThe frequency will be reducedThe wavelength will i...
- When light travels from air (a less dense medium) into water (a denser medium), it slows down and bends towards the normal line (an imaginary line perpendicular to the surface). This bending of light causes the pencil to appear bent at the water's surface. 5. Conclusion: - Therefore...

解析 A。本题考查宾语从句。“that”在宾语从句中只起连接作用,不充当句子成分,也无实际意义。“The experiment shows that light travels faster than sound.”意思是“这个实验表明光比声音传播得快。”“if”表示“是否”,“when”表示时间,“where”表示地点,均不符合题意。

As we know, scattering (散射) happens when light goes through the air. For the same media, if the wavelength (波长) is long, the scattering will be short. If the wavelength is short, then the scattering will be long.Of all light we can see red has the longest wavelength, so the ...
