1. Gamma rays are the highest energy EM radiation and typically have energies greater than 100 keV, frequencies greater than 1019 Hz, and wavelengths less than 10 picometers.
2. Loud sound has a high volume while soft sound has a low volume. Banging of a hammer and a car's horn are examples of loud sounds while playing of a piano and sound of blowing wind are examples of soft sounds
3. solids
The speed of sound depends on the medium in which it is transported. Sound travels fastest through solids, slower through liquids and slowest through gases.
4. transverse wave
Wave amplitude of a transverse wave is the difference in height between the crest and the resting position. The crest is the highest point particles of the medium reach. The higher the crests are, the greater the amplitude of the wave.
5.Radio waves have much longer wavelengths and lower frequencies than do visible light waves. In contrast, X-rays have much shorter wavelengths and higher frequencies. Likewise, red light has a longer wavelength than blue light.
