Heat lamps give off mostly?
Infrared waves.
What is the difference between Sound Reflection and Sound Refraction?
refraction is where the soubd waves bend, reflection is when sound waves bounce off of things and change direction.
What happens when electromagnetic waves encounters an object?
The waves ALWAYS do one, two, or all threeof these three things:pass through the object,get absorbed by the object,bounce off of the object.

Does the sun give off energy in waves which include radio waves light waves infrared waves and x rays?
Yes.
What type of energy does a computer give off?
Computers give off mostly heat, but also give off magnetism in the form of radio waves. Plus their displays give off light energy and the speakers give off sound waves. The fans inside create kinetic energy.

Stars that spin rapidly and give off radio waves are called?
pulsar
Do all objects in the universe give off radio waves?
As far as we know.
Do iron filings create waves when attracted by a magnet?
Magnetic waves are used to move the iron but the iron does not give off magnetic waves until it is touching the magnet
Why do mobile phones give off radio waves?
mobile phones give off radio waves to special stations which are built especially to connect calls, as they used to have an operator this is what now is used instead of the operator at this modernised age.
Can vibrators cause vaganal cancer?
no. The waves that vibrators give off are totally harmless
How radio waves harmful?
Radio waves are harmful to people because they give off radiation. Radiation is known to cause cancer in humans.
Do black holes give off radio waves?
Black Holes don't give off radio waves. They emit X-rays. This happens rarely since the black hole's gravity is so strong that it doesn't allow photons to escape.
