Examples of devices that involve electromagnetic waves that we can't see include radios, microwave ovens, and Wi-Fi routers. These devices use various frequencies of electromagnetic radiation to transmit signals or heat food, but the waves themselves are not visible to the human eye.

Which electromagnetic wave transfers the greatest amount of energy which type would transfer the least energy?

i think you cant classify electro magnetic waves. all em waves have sam energy.


Can compression waves be transmitted through a vacuum of space?

no the only waves that can go through space is the electromagnetic waves and it doesnt need sound or matter to travel.compressional waves have to come off of something and travel{like sound} it cant travel because there is nothing to travel through.the vacuum of space is just nothing and only light can go through as well, but it takes time.


How does light travel to one place to another?

by itself many scientists figured out that light travels by itself you can see light moving you cant touch it and cant hear it same with oxygen. oxygen is always around us we breath it and sometimes see it


Kind of electromagnetic radiation used to examining the inside of a weild in a steel oil pipe?

X-rays are commonly used to examine the inside of a weld in a steel oil pipe because they can penetrate the material and provide detailed images of the weld quality without damaging the pipe. This non-destructive testing method is effective in identifying any defects or inconsistencies in the weld that may compromise the integrity of the pipeline.


Why cant heat energy through space by conduction or convention?

Heat energy cannot travel through space by conduction or convection because space is a vacuum without any medium for heat transfer. In space, heat is mainly transferred by radiation, where electromagnetic waves carry energy from one object to another.

What materials reflect electromagnetic waves?

Any good conductor reflects lower frequency electromagnetic waves up through the microwave bands, polished surfaces (these do not have to be conductors) reflect electromagnetic waves in the IR/visible/UV frequency range, almost nothing reflects (except at very very shallow angles) x-ray/gamma ray electromagnetic waves.


Why cant sound waves travel through empty space?

Sound waves are mechanical waves, NOT electromagnetic waves. Mechanical waves need a substance to pass through, that is, they need some sort of surface to vibrate against to send compression waves through to the surrounding air. Electromagnetic waves however may travel through empty space as they have no need for a surface, instead, they need only electric and magnetic fields that are present in empty space to pass through. (vibrating electric fields will, in turn, vibrate the magnetic field, which will then trigger a nearby electric field to vibrate, which will make another magnetic field to vibrate, and this is how electromagnetic waves may travel through empty space, but mechanical waves may not)


What are 2 energy waves that cant be seen?

Heat waves (infared) and sound waves.


Why can radio waves travel through space but sound waves cant?

Sound waves are longitudinal waves that need a medium to propagate. This can be air,water or solids. Sound waves work like a truck hitting a line of cars. The wave travels through the line from back to front but would not if there were no cars. Radio waves, like light are electromagnetic waves and don't require a medium to radiate. That is why we see Sunlight but do not hear the constant roar of the Sun's fusion activity.


Can sound waves be reflected explain why they can or cant?

Is sound compression waves that can be heard?

yes i cant answer it


What cant secondary waves travel through?

Ocean


What happens when p waves and S waves try to pass through the outer core?

s waves cant travel through it


Why does UV radiation and radio waves have such different affects?

uv rays can give u sunburns but radio waves cant

Electric devices are not mentioned in the Torah, but it's part of the 39 prohibited tasks.
