Sunlight and radiowaves are examples of electromagnetic waves, which are transverse mechanical waves. Sound waves are compression waves.
Electromagnetic waves found in sunlight are light waves, ultraviolet waves and cosmic waves.
True. The up-down type of wave is called a "transverse wave". Light, for example, is this kind of wave. Sound, however, is a different kind of wave. It is the back-forth type, called "longitudinal", or "compression" waves.
sorta, compressions move at a slightly higher frequency, which is indirectly related to speed.
P-waves are faster than s-waves. Both can pass through solid rock, but only p-waves can pass through gases and liquids === ===
Sunlight is actually light waves of different frequencies. Some of these waves are part of the visible light spectrum (ROYGBIV), and therefore sunlight appears white, a combination of all the frequencies in the visible light spectrum. Light waves with lower frequencies appear more red or orange. Light waves with higher frequencies appear violet or blue. When sunlight shines down through the atmosphere, the particles in the air scatter the light waves of higher frequencies, therefore spreading the waves in different directions in the sky (This is why the sky appears blue). The lower frequency waves reach our eyes mostly undisturbed. Since sunlight has light frequencies dominant in yellow, that's the color we see.
Yes
sound waves are a example of mechanical waves
No. surface waves on the surface of water is transverse in nature. It has crests and troughs. Compression and rarefaction will be in longitudinal wave. example sound waves.
Radiowaves have the longest wavelength of all electromagnetic waves (which also includes visible light, and for example x-rays).
Radiowaves have the longest wavelength of electromagnetic waves.
Since radio waves are electromagnetic waves, the energy is stored in the electric and magnetic fields of space.
In 1887, Heinrich Hertz demonstrated the reality of electromagnetic waves by experimentally generating radio waves in his laboratory.
Visible light. (eg sunlight).
No
Waves in Air give a great example: they occur in two types - compression [compressed Air] and rarefaction [expanded or decompressed Air] Waves.
Primary waves / compression waves / longitudinal waves.
