Which sequence shows the different types of electromagnetic waves arranged in an increasing order of their frequency?

2 answers:

8 0

There is no sequence on your list that shows anything like that.

If you find a sequence that purports to do it, check and see that it
has radio first and gamma rays last. That sequence is a good bet,
although there can't be any guarantee until you all check all the others
in the middle.

How is the direction of light changed when it travels from an optically denser medium to an optically rarer medium????? please a

ANTONII [103]

Answer:

The light bends away from the normal

Explanation:

We can solve the problem by using Snell's law:

$n_1 sin \theta_1 = n_2 sin \theta_2$

where:

$n_1$ is the index of refraction of the first medium

$n_2$ is the index of refraction of the second medium

$\theta_1$ is the angle of incidence (angle between the incoming ray and the normal to the interface)

$\theta_2$ is the angle of refraction (angle between the outcoming ray and the normal to the interface)

We can rearrange the equation as

$sin \theta_2 = \frac{n_1}{n_2}sin \theta_1$

In this problem, light travels from an optically denser medium to an optically rarer medium, so

$n_1 > n_2$

Therefore, the term $\frac{n_1}{n_2}$ is greater than 1, so

$sin \theta_2 > sin \theta_1\\\rightarrow \theta_2 > \theta_1$

which means that the angle of refraction is greater than the angle of incidence, and so the light will bend away from the normal.

A fighter jet break the sound barrier what is the sound barrier and how can I get a break. Where does this sound around just con

Vikki [24]

Answer:

Sound barrier :

The sound barrier is defined as a "barrier" that travels in all directions (because we are talking about sound waves) at the typical speed of sound in the air (1235.5 km/h). It should be noted that the name of "barrier" was given because it was previously considered a physical limit that prevented large aircrafts from traveling at supersonic speed (a situation that was evident in fighter planes during World War II, having problems with compressibility when flying at high speeds). However, today many planes are capable of overcoming that barrier without problems.

When the Sound barrier is broken :

When an airplane approaches the speed of sound (defined in the upper lines), it can be observed how the shape of the air that flows around it changes, because the wave fronts are grouping more and more.

Then, when the plane exceeds the speed of sound (the sound barrier), something known as sonic boom or sonic explosion occurs, which is nothing more than what our ears can hear when the shock wave caused by the plane exceeds the speed of sound.

It should be noted that this explosion can be annoying to the human ear.
