What EM radiations travel the fastest from its source?
All electromagnetic radiation in a given medium (water, air, vacuum, etc) travels at the same speed, the speed of light in that medium.
What EM wave causes cancer?
Ultraviolet radiations cause cancer.
What em radiation has the lowest frequency?
Radio waves have the lowest frequency among electromagnetic radiations.
Do em waves need a medium?
no
Does an elecromagnetic wave need a medium?
No. Light is in the EM spectrum, and we can see light from the sun as space is a vacuum it can be concluded that EM waves do not need a medium.
What happens when EM waves encounter a material medium?
When electromagnetic (EM) waves encounter a material medium, they can be absorbed, transmitted, or reflected depending on the properties of the medium. The interaction between the EM waves and the medium can result in effects such as refraction, dispersion, or attenuation of the waves as they pass through the material. The behavior of EM waves in a material medium is determined by factors like the frequency of the waves, the composition of the material, and the electrical properties of the medium.
What is the amount a wave dependent on?
An energy wave is dependent on the energy input and the composition of the medium in which it moves.
Do em waves speed up or slow down when they travel through a medium?
EM waves typically slow down when they travel through a medium compared to their speed in a vacuum. This decrease in speed is due to interactions with the atoms and molecules in the medium, which cause the EM waves to be absorbed and re-emitted resulting in a slower overall propagation speed.
Does heat travel through a vacuum?
Actually heat cannot travel through vacuum. sun emits radiations (obviously electromagnetic radiations.) which needs no medium to travel. hence these radiations travel through space and reaches earth where it interacts with atmosphere. when these radiations fall on media like air, water land etc. the radiation is converted into heat energy. Thus it is clear that heat from sun is converted into radiations which travel through space and reaches earth where it is converted to light.
How is the EM spectrum applied to science?
EM spectrum involves all radiations of different wavelengths. This has been very useful in studying various things in the field of science. Certain range of wavelengths are also very important in critical analytical techniques.
Is a EM wave a sound wave?
No, electromagnetic (EM) waves are different from sound waves. EM waves are vibrations of electric and magnetic fields that do not need a medium to travel through, while sound waves are mechanical vibrations that require a medium, such as air or water, to propagate.
Is the speed of sound dependent on frequency?
No, the speed of sound is not dependent on frequency. It is determined by the medium through which the sound waves travel.
