Which of the following is not an EM wave?
2 answers:
Answer:
D. Sound
Explanation:
<u>Waves</u>: one of the ways that energy may be transferred. Waves can be described as oscillations.
Electromagnetic (EM) waves are <u>transverse waves</u>.
EM waves can be separated into <u>seven groups</u> in the spectrum. From long wavelength to short wavelength:
- Radio waves
- Microwaves
- Infrared
- Visible light
- Ultraviolet
- X-rays
- Gamma rays
Sound waves are <u>longitudinal waves</u>.
The direction of oscillations is <em>different </em>between longitudinal and transverse waves:
- <u>Longitudinal waves</u>: the vibrations are parallel to the direction of wave travel.
- <u>Transverse waves</u>: the vibrations are at right angles to the direction of wave travel.
Answer:
Sound
Explanation:
EN waves are known as electromagnetic waves
- They can be identified from the electromagnetic spectrum
They are divided into seven parts
- Microwaves
- Radiowaves
- Visible light
- X-rays
- UV rays
- Gamma rays
- Infrared
We can only watch Visible light not others .
Sound is not transverse wave

Answer:
1. Primary or P waves are push and pull waves
2. Secondary, S or Shear Waves are also called transverse wave
3. L or surface waves reach the earth's surface after P and S waves
