Firstly, any form of radiation is harmful to the body because it causes cellular aberrations and genetic mutations which may ultimately lead to cancer. As for sun radiation, so long as you don't get yourself too overexposed there's really nothing to worry about. in fact the sun is helpful in the activation of vitamin D. just a tip, the best time to go out for a little sun would be early in the morning and later in the afternoon. However, staying in the sun for too long over the years without wearing a hat, suncreen, sunglasses, protective clothing or staying in the shade can increase your risk of getting skin cancer.
Did You Know: Getting sunburnt 5 times each Summer increases your risk of skin cancer by 10%
radio waves
Radio waves. Low frequency.
light waves do not need a medium. Electromagnetic Waves (EM) do not need a medium. For example visible light, radio waves, microwaves, UV light and x-rays do not. These travel @ 300 million meters/sec in a vacuum.
A triode works as a basic amplifier by the use of radio waves. The radio waves produce a heat that is amplified.
That means that both the frequency and the wavelength of microwaves are also between those of infrared and radio waves.
Here are a few things that radio waves can do: 1. Communications (TV, Commercial radio, Ham radio etc.) 2. Heat things up, (Microwaves are just extremely short radio waves) 3. They can travel extremely fast (At the speed of light)

Not very. As far as I know there's no real evidence that radio waves cause any measurable harm to people.
they use radio waves to pick up some what satellite images or existance of things in space
Not Really Broadcasting Republican Propaganda
The're really low frequency and can be easily disrupted by buildings and things like that. AM radio uses these electromagnetic waves to broadcast stuff.
no, mechanical waves are not radio waves
Radio waves ARE electromagnetic waves.
Transverse. Radio waves are electromagnetic waves, which are transverse.
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.
Some good effects of FM radio is that people have access to free news, music, and can be alerted to emergencies. One possible bad effect of FM radio is that some scientist think radio waves may be bad for humans.
it causes gamma waves ,visible light ,radio waves.
