Which wave property changes when two waves interfere in the same medium?

<span>When two waves of same frequency travel in a medium simultaneously in the same direction then, due to their superposition, the resultant intensity at any point of the medium is different from the sum of intensities of the two waves. At certain points the intensity of the resultant wave has a large value while at some points it has a very small or zero. This is called wave interference.</span>

Using what you know about air pressure and the water cycle, explain how hurricanes form. Why are there certain places on Earth m
Yuki888 [10]
Hurricanes form when hot air and cold air start colliding above water and they start to form a tornado but there is water in the tornado. Certain places on earth are more susceptible to hurricanes because they are closer to the coastlines. For example, in Iowa, and Illinois, they have a lower chance of a hurricane, while Florida, and Washington have a higher rate because they are along the ocean. Hope this helps.

Answer:

Radio waves have a wavelength between 10^{-9}m and 10^{-12}m

While,

X rays have a wavelength between 1m and 10km.

=> It is one of the condition of diffraction that the obstacle (coming in the way) must be comparable with the size of the wavelength.

=> This shows, that radio waves have a wavelength which is comparable with the size of buildings and can really easily diffract through it

=> While, X-rays are big enough to diffract through the wall.

So, if an X-ray technician stands behind a wall during the use of her machine, she will remain safe.

Fine grains of beach sand are assumed to be spheres of radius 49.8 µm. these grains are made of silicon dioxide which has a dens
PIT_PIT [208]

Answer:1.3\times10^{-9}kg

Volume of each grain of sand:

V=\frac{4}{3}\pi r^3

radius of the spherical grain is given,r=49.8\mu m=49.8\times10^{-6} m

\Rightarrow V=\frac{4}{3}\times3.14\times(49.8\times10^{-6})^3m^3=5.17\times10^{-13}m^3

The grains are made up of silicon dioxide.

The density is equal to D=2600 kg/m^3

Then, the mass of each grain is given by:

Mass=Density (D)\times Volume(V)\\ \Rightarrow M=2600 kg/m^3\times5.17\times10^{-13}m^3 =1.3\times10^{-9}kg
