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.

The dark bands on the wall are from ______________ interference. and i will give brainlyest

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, the dark bands on the wall are from destructive interference.

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:

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

Where:

F is the frequency of a sound wave.

V is the velocity of a sound wave.

$\lambda$ is the wavelength of a sound wave.

Note: 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.

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.
Since Na^+ is a positive ion (cation) with a charge of +1, it indicates that it has lost an electron. 
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. 
Therefore, the Lewis dot structure for Na^+ is just Na^[+]
