One of the characteristics of light is that it behaves like a wave. As a result, light can be defined by its wavelength and frequency. The frequency is how fast the wave vibrates or goes up and down. The wavelength is the distance between two peaks of the wave. Frequency and wavelength are inversely related, meaning that a low frequency wave has a long wavelength and vice versa.
When light hits a surface, some of it is absorbed and some of it is reflected. The light that is reflected is the colour of the object in that light. For example, a blue object absorbs all the colours of the spectrum except blue: it reflects blue light. Visible light waves are the only electromagnetic waves we can see. We see these waves as the colors of the rainbow. Each color has a different wavelength. Red has the longest wavelength and violet has the shortest wavelength. When all the waves are seen together, they make white light. When white light shines through a prism or through water vapor like this rainbow, the white light is broken apart into the colors of the visible light spectrum.
Cones in our eyes are receivers for these tiny visible light waves. The Sun is a natural source for visible light waves and our eyes see the reflection of this sunlight off the objects around us.
The color of an object that we see is the color of light reflected. All other colors are absorbed.
Light bulbs are another source of visible light waves.
Hope this helps :)
Its due to erosion. Erosion slowly breaks down everything down, that why we have places like The Grand Canyon.
No, it is false that the United States and the United Nations successfully restored peace in Somalia in the 1990s, since Somalia is still a very dangerous and unstable land.
Answer:
50-64
Explanation:
China is the nation with the largest population in the world, and that has been the case throughout all of the written history, and probably even before that. The country had very large birthrates, which was leading to rapid growth to the population. Because of that, there was even a law that restricted the families as to how many children they can have. Because of that law, the population of China started to gradually age, so the percentage of the younger age groups has been declining, while the percentage of the older age groups has been on the rise. This has led to the age group of 50-64 to account for 120 million people in China, a percentage that has grown almost twice compared to several decades prior to that.
