Raindrop makes in still water are circles why do they make circles?
Waves transfer energy outward equally. Since there is no barrier to the water, when a raindrop hits the water that energy of the raindrop falling has to go somewhere, the energy is transferred from the raindrop to the water and goes outward from the epicenter (where the raindrop fell). The waves (circles) will continue to travel an equal distance unless there is an outside force such as wind, another object, ect. to stop the wave
An example how trigonometric functions are used to explain a real life occurance?
The obvious answer is the relationships between the sides and angles of triangles. Waves in the sea are an example of a sine wave. Tidal Experts and Meterologists alike use sine waves to help predict tides. Music will also emit waves that may often look like a sine wave and pure notes will look like sine or cosine waves. The speed of a swinging pendulum can be plotted as a sine wave as well as the sound of a tuning fork. Electromagnetic radiation (from a mobile phone, GPS, car radio ect) also moves in sine waves.
How is irrational number used in science?
Many physical laws, particularly those dealing with forces or electromagnetic have an inverse square relationship. So, if you want to know how far you need to be before a light seems half as bright, the answer is to the distance of sqrt(2) times. The formula for all harmonic motion - vibrations - including electromagnetic waves such as light and electricity involve pi. The decay rate for radioactive nuclei, population growth for bacteria etc involve Euler's constant, e. Basically, you would not get anywhere in science without irrational numbers.
Why does hydrogen spectrum contains 4 coloured lines why not 3 or 7?
In theory, hydrogen has infinitely many spectral lines. The "Balmer series" has four lines in the visible spectrum; additional lines are in the ultraviolet. Other "series" have other lines - it seems that all of them are either in the ultraviolet or infrared. For more information, read the Wikipedia article on "Hydrogen spectrum". The reason there are four VISIBLE lines is basically chance - an excited hydrogen atom emits light at certain frequencies (which can be calculated, see the article for more details); our eyes see a certain range of electromagnetic waves that happens to include four of those lines.
Is Nikola Tesla smarter than albert Einstein?
In my opinion yes; he invented direct current ,which was stolen by Edison, alternating current, remote control technology, radio waves, incandescent bulbs, wire less power ,which he never had the funding to complete, and many other inventions way out of there time in his lost journal, some rumored to be an earth quake machine. Another of his ideas was haarp a signal station that can bend the jet streams using radio frequencies to over heat the air and change and direct the climate. All Einstien did was relativity and the nuclear bomb while those are truly genius accomplishments compairing Tesla to Einstien would be like comparing Newton to DaVincii
Waves that require a medium through which to travel are called electromagnetic waves True or false?
False. Electromagnetic waves do not require a medium to travel; they can propagate through a vacuum.
When waves travel through a medium they carry the medium with them is this true or false?
False. Waves do not carry the medium with them as they travel through it. Instead, they transfer energy through the medium without permanently displacing the particles of the medium.
Is this true or false mecanical waves din't need matter to travel through?
False. Mechanical waves require a medium (such as air, water, or solid material) to propagate. They transmit energy through the vibration of particles in the medium. Examples of mechanical waves include sound waves and seismic waves.
Is mechanical waves can travel though empty space true or false?
False. Mechanical waves require a medium, such as air or water, to travel through. They cannot propagate through empty space because they rely on the vibration of particles in the medium to transfer energy.
What type of wave requires no medium to travel through?
Waves need not require medium to travel through. Only Mechanical waves like sound waves require medium to travel through. Electromagnetic waves travel in vaccum like light waves. Some waves transmitted in a medium due to disturbances in the medium .
What waves need a medium to travel in?
Mechanical waves, such as sound waves, require a medium to travel through. These waves propagate by causing particles in the medium to vibrate and transfer the energy of the wave. Electromagnetic waves, such as light waves, do not require a medium and can travel through a vacuum.
Do radio waves need a medium to travel through?
No, radio waves do not need a medium to travel through. They are a type of electromagnetic wave that can travel through a vacuum, such as space. They can also travel through other mediums, such as air or water.
What waves do travel in a medium?
Mechanical waves, such as sound waves and seismic waves, travel through a medium by transferring energy from one point to another through oscillations of particles in the medium. These waves require a medium (solid, liquid, or gas) to propagate and cannot travel through a vacuum.
Does transverse wave require a medium to travel through?
Yes, transverse waves require a medium to travel through. Examples include water waves, which need water as a medium, and electromagnetic waves such as light, which can travel through a vacuum.
is An electromagnetic wave is a mechanical wave/true or false?
False. An electromagnetic wave is not a mechanical wave; it is a type of wave that can travel through a vacuum, such as light or radio waves. Mechanical waves, on the other hand, require a medium to travel through, like sound waves traveling through air or water waves traveling through water.
What are three medium waves can travel through?
Not all waves require mediums to propagate.Sound waves can travel through solid, liquid and gaseous mediums, while, electromagnetic waves do not require any medium to travel through.
Do surface waves require a medium?
Yes, surface waves require a medium to travel through. Unlike electromagnetic waves that can travel through a vacuum, surface waves, such as water waves and seismic waves, need a material medium to propagate.
