Is it true or false that the frequencies of radiation increase as the wavelengths increase?
FALSE
Is the following sentence true or false when the particles of an object move faster its thermal energy increases?
False
Orchestration is always done by the conductor.?
false
Solid metals undergo greater thermal expansion than liquids do?
false
True or false radiation is the only method of energy transfer that can take place in a vacuum?
if there is radiation in the vacuum, then it's not really a vacuum.
Black body radiation of the emission o light from metal surfaces false or true?
False. Black body radiation refers to the emission of light from an object that absorbs all incident radiation. While metals can emit light, the term "black body radiation" specifically refers to the emission from an idealized object, called a black body, which is not typically applicable to metal surfaces.
A person exposed to radiation has no chance of survival. true or false?
False. We are often exposed to low dose radiation.
Is it true or false that the frequencies of radiation increase as the wavelengths increase?
FALSE
Is it true or false that electricity is a form of fire?
FALSE. (they are different forms of energy) "Fire" is a release of thermal energy from a chemical or electro-chemical reaction. The ensuing radiation can have visual components (photons) as well as infra-red radiation (heat). "Electricity" is the conductive flow of electrons through a material, medium, or vacuum. Energized electrons (current) flow into a material or device at the anode and out at the cathode.
Are animals are not affected by radiation true or false?
false. All animals are affected by radiation. Some can withstand more than others like cockroaches.
Is the following sentence true or false when the particles of an object move faster its thermal energy increases?
False
True or false cellular phones produce radiation?
True - they work by using microwave radiation.
Does RF radiation causes the same types of biological harm as X-ray radiation?
no false
Cancer is cause by radiation true or false?
true
A person exposed to radiation has no chance of survival?
false because sunlight has radiation and all living things like humans has radiation
Energy is usually transferred in fluids by radiation true or false?
False radiation is the transfer of energy through space.
True or false on a cold day particles of air have more thermal energy than they have on a warm day?
false
