Answer:
Red light waves
Explanation:
Electromagnetic waves are transverse waves composed by the perpendicular oscillating electric and magnetic fields.
EM waves have both Electrical and magnetic features.
they travel in the velocity of light (3*10⁸ ms⁻¹)
Electromagnetic spectrum is obtained according to their wave length and the frequency. Due to wave length range it's categorized. Here is the decreasing order of wave length and increasing order of different wave types in electromagnetic spectrum
- Radio Wave
- Micro Wave
- IR wave
- visible light
- UV rays
- X rays
- Gamma rays
- Cosmic rays
Electromagnetic waves does not need any media to travel but mechanical waves need a media to travel .
visible light can be further divided as of in the graph
When you consider the red ray. Red ray is sub section of light rays. That's why we can see red rays. since they do not use any media to travel, we can get light rays from sun easily
N
But ocean waves sound waves , Earthquake waves can be classified in mechanical waves. There should be a medium to travel waves for those three waves. Otherwise they cannot
