How can describe electromagnetic waves with mechanical waves?

<span>Mechanical waves are mostly longitudinal waves. It means the constituents of the naterial through which the wave is moving are oscillating in the same direction as the wave itself.

In an electromagnetic wave the motion of the electric and magnetic fields is transverse to the direction of propogation of the wave. So the E, B and k vectors are perpendicular to each other. Also unlike a mechanical wave, an electromagnetic wave does not require a medium to travel. It can travel in completely empty space.

The matter wave or de Broglie wave comes from the wave particle duality of a quantum mechanical object such as an electron or an atom etc. This wave can also travel in empty space. Due to the strange nature of quantum mechanics, a quantum object manifests itself as a particle or a wave depending solely on the type of measurement or observation. So for example if one lets a stream of single electrons to fall upon 2 closely spaced slits then each electron would behave as a wave and lead to interference fringes on the screen behind the slits.</span>

Firdavs [7]

Answer:

Dana filtered the sample and larger granules of the sample were left behind.

Explanation:

If a substance is pure, it will have a uniform composition throughout. It will not separate into particles of various sizes.

One of the characteristics of pure substances is that they are homogeneous. A mixture is definitely made up of particles of various sizes.

Since the particles was filtered and larger granules were left behind, the sample has been separated by a physical method (filtration). Only a mixture can be separated by physical methods. It is not a pure substance.

Which of the following is an example of mechanical weathering
777dan777 [17]
The answer is A-Gravity. Why? This is because B and C are examples of chemical weathering and not mechanical. Although choice D may seem viable lava intrusion is not a direct cause of mechanical weathering although lava pushing upward may help in aiding mechanical weathering it would not be considered a big enough cause, thus gravity is the correct answer.

The temperature of a gas is 30 degrees Celsius and its pressure is 760 torr. If the temperature originally
erastova [34]
T₁ = 40°C + 273.15 = 313.15 Kelvin T₂ = 30°C + 273.15 = 303.15 Kelvin

Solving Gay-Lussac's Law for P₁ we get:
P₁ = P₂ • T₁ ÷ T₂ P₁ = 760 torr • 313.15 K ÷ 303.15 K P₁ = 785.07 torr

Using the calculator, we click on the P1 button.
We then enter the 3 numbers 760 313.15 and 303.15 into the correct boxes then click "CALCULATE" and get our answer of 785.07 torr.
