Radio waves are harmful to people because they give off radiation. Radiation is known to cause cancer in humans.
Radio waves aren't harmful at its usual pattern of operation. They are harmful only when a strong signal is close to a person. It can cause cancer and other problems. Radio waves may also cure. All waves have different results.
there jedd
it releases harmful radio active waves which s harmful to all living organism
not for a long time. they are not very harmful as they have a long wavelength and a low frequency.
They have low energy, long wavelength so they aren't harmful.
Radiation generally describes non harmful waves such as radio waves and light wave while nuclear radiation usually describes emission of harmful gamma rays.
no, mechanical waves are not radio waves
Transverse. Radio waves are electromagnetic waves, which are transverse.
Light waves do diffract, but the effect is very very small. In general diffraction effects are important when the object interacting with the wave has dimensions that are comparable to the wavelength of the wave. Light waves have much shorter wavelength compared to the radio waves. Hence the effect. (It should also be noted that radio waves penetrate buildings much better than light waves, but that leads to a more nuanced discussion of diffraction effects.)
Radio waves ARE electromagnetic waves.
No. Radar waves are one category of radio waves. Think of all the radio waves that are all around you right now . . . AM radio, FM radio, police and fire radio, highway patrol radio, taxi radio, television picture and sound radio waves, cellphone radio waves, garage-door-opener radio waves, bluetooth radio waves, WiFi waves, microwaves ... and you can't see any of them ! Radar waves can easily be there in the group.
