What band of the electromagnetic spectrum can be diffracted most easily?
Gamma rays can be diffracted most easily.
What is a wavelength region in which electromagnetic energy comes through the atmosphere easily?
Almost the whole of the E-M spectrum is easily transmitted through the atmosphere, apart from a band of frequencies from about 1.5 MHz to 10MHz . This narrow band will be interfered with by the ionized layers high in the atmosphere. The characteristics of this band depend on the nature of the Solar Wind, and upon disturbances of the Earth's magnetic field. Infrasonic E-M radiation at the low frequency end will travel through easily, as will microwave frequencies. And continuing on to light, and cosmic rays at the highest end of the frequency spectrum.
What is the purpose of electromagnetic spectrum?
The electromagnetic spectrum is simply a way to display the range of electromagnetic energies in a manner that some associations can be discovered. Electromagnetic (EM) energy is composed of two waves, one electrostatic and one electromagnetic, that propagate at right angles to one another. Since we are looking at waves, it is natural to consider that they have different periods (the time it takes for one cycle to occur). We can then extend our thinking to consider the length of the wave, and also the frequency (the number of cycles per second) of the energy. Finally, we can consider the energy that is being propagated in the wave. If we spread out all the different frequencies on a chart or diagram with the lowest frequencies to the left and the highest frequencies to the right (as we usually do), we have a display of the electromagnetic spectrum. Radio waves will be on the left. They have the longest wavelength and the longest period, and also the lowest frequency. A lot of the spectrum is taken up by radio waves. Further to the right come microwaves, then the EM radiation a bit lower in frequency than visible light, which is the infrared region of the spectrum. The optical spectrum (visible light) is represented by the reds, oranges, yellows, etc., that we who are fortunate to be sighted can know. Beyond the violet visible light is the ultraviolet region, and then soft (lower energy) X-rays, and then the hard X-rays. Finally we find the gamma rays at the upper end of the spectrum. Looking at all of the diagram, which is a representation arranged to a useful purpose, we can discover a number of things about electromagnetic energy. The different spectra (radio, microwave, etc.) all have distinct characteristics that we can apply in daily life. Low frequency radio waves are used in submarine communication. (They penetrate water to a degree, and can actually travel in a curve around the world.) Microwaves make your cellular phone work, and they heat food in a microwave oven. We (most of us) are visual creatures, and visible light from the optical spectrum allows us to navigate our way about. At a medical clinic, hospital or dental office, an X-ray allows health professionals to quite easily see things that cannot be looked at well with other methods. There is a lot to learn, and a display of the electromagnetic spectrum opens a door to understanding this type of energy.

What are three examples of noncontact forces?
A sound field, an electrical field, a magnetic field, and a gravity field would all be examples of non-contact forces. But though their effects are 'non-contact' their presence may nevertheless be easily detected.
What band of the electromagnetic spectrum can be diffracted most easily?
Gamma rays can be diffracted most easily.
Which region of the electromagnetic spectrum can easily reach a telescope on the earth's surface?
Visible light.
Is temperature easily detected in stars?
You can get a rough idea of a star's temperature by its color. A detailed analysis of the spectrum can give additional information.
What rays easily detected by a thermometer?
Infrared Rays are easily detected...
Why Solids cannot be compressed easily whereas gases can easily compressed?
The molecules of a solid are as close together as they can get using electromagnetic force (that all you've got - including machines) ... whereas gas molecules are relatively far apart.
Can nicotine in cigars be detected by existing methods as easily as in cigarettes?
Yes , nicotine is easily detected by modern means .
Which type of electromagnetic wave will be emitted by a hotter object?
Hot objects emit electromagnetic waves at frequencies in a wide range starting from the infra-red, which is invisible to humans but is easily detected by other animals and man-made heat-detector instruments, up to higher, visible light.
Where can a pulse can be detected most easily in?
In the arteries
When there is no wind the scent of flowers can be detected more easily on a warm night than on a cold night?
Yes. This is because the molecules of the scent condense nearer to the flowers than in colder conditions.
Hydrogen molecules and oxygen molecules can be easily split by what?
Hydrogen molecules and oxygen molecules can be easily split by what electrolysis. This is the process which is used to breakdown water.
What food molecules is easily absorbed?
Vitamin C molecules, water molecules and glucose molecules are very easily absorbed because they don't have as many particles as starch molecules, protein molecules and fat molecules.
What types of molecules dissolve easily in water?
Polar molecules and ions dissolve easily in water
