Distinguish between constructive wave interference and destructive wave interference.

Physics
1 answer:
Kamila [148]3 years ago
8 0

Explanation:

The phenomenon of superimposing of two waves such that the resultant wave have greater, lower, or the same amplitude.

There are two conditions for the interference.

  • Constructive wave interference: This type of interference occurs after adding of two maxima such that the amplitude of the resulting wave is equal to the sum of the amplitudes of individual waves.
  • Destructive wave interference: In this type of interference,  the amplitude of the resulting wave gets reduced as the crest of one wave meets with the trough of another wave.

Fittoniya [83]
Light can be seen as an electromagnetic wave.
What happens when two waves, with the same frequency, superpose is called interference.

If at a certain point two waves arrive both with a crest, we have constructive interference and the amplitudes sum up, reaching the maximum value, resulting in bright spots.

If at a certain point one of the waves arrives with a crest and the other wave arrives with a trough, we have destructive interference, and the two amplitudes cancel out, resulting in dark spots.

Therefore, t<span>he dark bands on the wall are from destructive interference.</span>

If you increase the frequency of a sound wave four times, what will happen to its speed?
ozzi

The speed will increase four (4) times when the frequency of sound wave is increased four (4) times.

<h3>How to calculate the frequency of a wave.</h3>

Mathematically, the frequency of a sound wave is given by this formula:

F = \frac{V}{\lambda}

<u>Where:</u>

  • F is the frequency of a sound wave.
  • V is the velocity of a sound wave.
  • \lambda is the wavelength of a sound wave.

<u>Note:</u> The frequency of the sound wave is increased four (4) times.

  • F = 4F

Substituting the given parameters into the formula, we have;

4F = \frac{V}{\lambda}\\\\V=4F\lambda

Therefore, the speed will increase four (4) times when the frequency of sound wave is increased four (4) times.

finlep [7]

Answer:

Creative thinking

Explanation:

As you can see in the question above, when Mandleev needed to organize the chemical elements in a logical, organized and efficient way, he thought until he came to the conclusion of organizing them according to the atomic weight of each one. This is a clear example of creative thinking, which is the term that refers to the act of solving a problem based on thought and reasoning.

What is the lewis dot structure of Na+
SpyIntel [72]
The dots in the Lewis dot structure symbolize an atom's elements. 
<span>Since Na^+ is a positive ion (cation) with a charge of +1, it indicates that it has lost an electron. </span>
<span>Since Na had one electron, to begin with, and it is now lost, Na^+ will have no dots. However, the charge must still be written as a superscript. </span>
<span>Therefore, the Lewis dot structure for Na^+ is just Na^[+] </span>
