Answer:
1. 1 Angstrom = 10-10 meters. The order of colors in light, arranged from shortest wavelength to longest, is called the visible spectrum of light. The image below shows light's visible spectrum, which runs from violet to red. You might recognize the spectrum as the order of colors in a rainbow.
2.Arrange in decreasing order of wavelengths : X-rays, gamma rays, UV rays, Red light, Micro waves, Infrared, Radio waves, Violet light.
3.The visible light portion of the electromagnetic spectrum shows the rainbow of colors, with violet and blue having shorter wavelengths, and therefore higher energy. At the other end of the spectrum toward red, the wavelengths are longer and have lower energy
4.The lower the frequency is, the less energy in the wave.
