1 is The greater the energy, the larger the frequency and the shorter (smaller) thewavelength. Given the relationship between wavelength and frequency β the higher the frequency, the shorter the wavelength β it follows that short wavelengths are more energetic than long wavelengths.
2 is he Sun & its Energy. The sun's energy is the primary source of energy for all surface phenomena and life on Earth.
Combined with the material of the Earth (including the molecules held close by the Earth's gravitational force called the atmosphere), this energy provides for the immense diversity of life formsthat are found ...
3 is The light that we see is a type of electromagnetic radiation. However it is only a very small part of the entire electromagnetic spectrum. Sound, another form of energy, is not part of this spectrum.Electromagnetic radiation is different from sound in that it can travel in space and does not need a medium like air or water to travel
