What minimum distance should you separate two sources emitting the same waves with wavelength 5mm in phase such that you obtain
Makovka662 [10]

To solve this problem we will apply the concept related to destructive interference (from the principle of superposition). This concept is understood as a superposition of two or more waves of identical or similar frequency that, when interfering, create a new wave pattern of less intensity (amplitude) at a point called a node. Mathematically it can be described as

d = n \frac{\lambda}{2}

Where,

d = Path difference

\lambda= wavelength

n = Any integer which represent the number of repetition of the spectrum

In this question the distance between the two source will be minimum for the case of minimum path difference, then n= 1

d = \frac{\lambda}{2}

d = \frac{5*10^{-3}}{2}

d = 2.5mm

Therefore the minimum distance that should you separate two sources emitting the same waves is 2.5mm

What's the dielectric constant of ceramic?<br> A. 1,200<br> B. 900<br> C. 80<br> D. 7.500
I am Lyosha [343]

Answer:

7.5

Explanation:

The dielectric constant of ceramics is about 7.5.

The dielectric constant of a substance is the ratio of the electric permeability of a substance to the electric permeability of free space.

Dielectric constant gives a good overview about the ability of substance to store charges compared to another.

Most substances have their electric constant and they suggest the ease by which they can store electrical energy. This is very important in developing capacitors.
