Answer:
<u>visible portion of the spectrum</u>.
Explanation:
- EMS consist of a range of the spectrum that is emitted from the sun in various forms that reach the human eye.
- Some day to day spectrums are
- Radio
- Microwave
- Infrared
- Visible
- Ultraviolet
- X-ray
- Gamma-ray
- Visible light is a combination of primary colors like the blue, green and red that reach the eyes of the observer from a distance from 380 to 740 nanometers.
- Having a larger wavelength that passes through the depths of the atmosphere and reaches the optics through the scattering a well as medium and longer wavelength. The longest wavelength in visible light is red and the shortest wavelength is of violet.
According to modernization theories, endogenous factors in the countries, such as traditional, illiteracy, the traditional attitude of the population, agrarian structure, the low division of labour, the lack of communication and infrastructure, etc., are answerable for underdevelopment.
the major effects of the earth’s revolution is not that there are seasons (contrary to what some reserve teachers think), which are caused by the axis tilt. however given that the axis tilt is responsible for seasons, the orbit around the sun will make them repeat themselves once per amount of time the earth takes to orbit. the earth’s REVOLUTION will also mean that we see different groups of stars at night over the course of a year. the earth’s revolution around the sun also enables us to measure the distances to nearby stars using the mathematical concept of PARALLAX. The earth’s motion needs to be separated out from our observations about motions of other objects, for example, retrograde motion of planets like Mars, Jupiter and further planets are the result of the earth traveling faster than they do as we overtake them.
