If you take a bearing of position 2 using a compass at position 1
then take a bearing of position 1 from position 2 then they should be reciprocals
180 degrees difference if there is any other magnetic field apart from earths then there will be a difference other than 180 degrees.
Electromagnetic waves better known as light is used by humans in a multitude of ways. We use visual light to see, thermal energy to degree temperature, radio waves to send signals, x-rays to take pictures of inside the body, different light waves for microwaving, the sun mostly gives off Ultra-violet waves which helps with vitamin D and sun tanning.
More technical, atoms are held together via the electromagnetic field. Electrons and protons communicate with photons (light). With this ability, molecules bind together to create materials humans use everyday.
Radio receivers and TV sets use antennas to detect EM waves.
Telescopes can detect EM waves.
Each type of telescope can only detect one part of the electromagnetic spectrum. There are radio telescopes, optical (visible light) telescopes, infrared telescopes and so on. We can't see most of the radiation detected, so computers turn data into images we can see.
Astronomers have a problem detecting radiation from space because the Earth's atmosphere blocks most of it and stops it from reaching the surface. Visible light and radio waves get through to telescopes on the ground, and some detectors (infrared, UV and gamma) work when they are high up on mountains. The best place to detect most radiation is above the blocking atmosphere, so some telescopes are put in orbit around the Earth. Even visible light is distorted by the atmosphere, so clearer pictures can be got from orbiting telescopes. the Hubble Space Telescope is positioned outside the Earth's atmosphere and takes very sharp images of very distant objects in space.

You take a magnet and put it in front of a compass to see its magnetic surfac and electromagnetic waves.
radio waves are detected by using radio receiver

The answer to that question depends heavily on who "he" was.
Electromagnetic waves or radiation. "Light," however, generally refers to that portion of the EM spectrum that our eyes can detect.
EM waves stand for Electromagnetic waves.
EM waves or electromagnetic waves is radiant energy.
EM waves are both Transverse and Longitudinal.

Normally, we detect sound by listening with our ears. As sound is waves, there are instruments that can detect and show the waves on a screen.
Radio waves
Electromagnetic waves have no odor.
The difference is in the different waves' frequency - therefore, the wavelength is also different. Our eyes are adapted to seeing specific frequencies; we can't see, or detect, just any type of EM wave. Mechanical waves are unrelated to EM waves, except that both are waves, and therefore share certain characteristics (having phenomena such as interference, polarization, etc.)
