How the different types of waves are form and how the waves travel

1 answer:

4 0

There are 2 types of waves mechanical and electromagnetic, mechanical waves need a medium to travel energy, while an electromagnetic wave doesn’t not require a medium. Electromagnetic waves travel through the vacuum(space). Electromagnetic waves include : radio waves, microwaves, infrared radiation, visible light, Ultraviolet light ( UV light), x-rays, and gamma rays, all of those are transverse waves. Mechanical waves are separated into 2 waves longitudinal and transverse. Transverse waves travel up and down while longitudinal waves travel back-and-forth

When a wave strikes a new medium, three things can happen: reflection, transmission, and absorption. Consider an echo. Do you th

kolbaska11 [484]

Answer:

YES

Explanation:

An echo may be defined as a sound which is repeated because of the sound waves that are produced are reflected back after striking a surface. Sound waves can smoothly bounce off the hard objects in the same manner as a rubber ball bounces back the ground.

When a sound wave strikes a hard surface, the sound waves gets reflected back and bounces back to the observer and produces an echo. If the sound waves strikes a soft surface it absorbs the sound.

Although the direction of a sound changes but the echo sounds in the same way as the original sound.

Objects with Relative density greater than 1 will sink in water. As you can see here, solution has density greater than 1( density = mass/volume = 43/35 = 1.22 g/ml). Hence solution will suspend at the bottom of the beaker. So option A is correct. Hope this cleared your doubt!

You have two solid blocks of metal wrapped in paper. The blocks are the same size, but one is pure aluminum and the other is pur

puteri [66]

Answer:

We can identify easily which block has more density, if we try to lift each one, and the heavier will be the one with more density. In this case the block of iron will be the one with more density.

Explanation:

To understand this we will give some numerical values to give the best explanation of this situation.

Let's say that we have the two blocks over one table, and over the table there is a special scale to measure the mass of an object.

Both block have the same dimensions, and seaching information of density by internet we find that the density for the iron is 7850 [kg/m^3], and the density for the aluminum is 2712 [kg/m^3]

Now the dimension of each bloack are 10*10*10 [cm] so, the volume will be 1000 [cm^3] = 0.001[m^3]

Now using the expression of density:

$density = \frac{m}{v} \\where:\\m = mass [kg]\\v= volume [m^{3} ]\\m = density* volume$

for the iron

$miron=7850*0.001 = 7.85 [kg]\\$

for the aluminum

$malumi=2712*0.001=2.712[kg]$

Therefore the weight of the iron will be always almost 3 times heavier than the weight of the aluminum.
