<u>Answer</u>:

When light passes through an object unchanged, scientists call that process Transmission.

<u>Explanation</u>:

Transmission is the process where all the light that is passed through the material moves via the material without being absorbed. The Transmission depends on the affected radiation.The Transmittance of the medium is defined as the ratio between transmitted radiant power and incident radiant power. The light that is passed through the medium and not reflected will be either scattered or reflected. The light can be transmitted only through transparent or translucent material. Opaque object does not allows transmission of light.

Is the refractive index constant?

Vlad [161]

Answer:The refractive index (n?) of a material is defined as the ratio of velocity of light in a vacuum to that in a defined material. The refractive index of a glass is not a constant, but depends on the wavelength of the incident light, known as dispersion

In the diagram, q1 = -3.33*10^-9 C and

Anna [14]

Answer:

The distance will be "0.319 m".

Explanation:

The diagram of the given question is not attached with the problem. Below is the attached figure.

The given values are:

$q1 = -3.33\times 10^{-9} \C$

$q2 = -5.22\times 10^{-9} \ C$

As we know,

The electric field will be equivalent as well as opposite throughout the direction, then

⇒ $\frac{R.q1}{(0.255)^2} =\frac{R.q2}{r^2}$

⇒ $r^2=\frac{q2}{q1}\times (0.255)^2$

By putting the values, we get

⇒ $=\frac{-5.22\times 10^{-9}}{-3.33\times 10^{-9}}\times (0.255)^2$

⇒ $=1.568\times 0.065$

⇒ $r^2=0.10193$

⇒ $r=\sqrt{0.10193}$

⇒ $0.319 \ m$

Which element does not nomally form chemical bonds?

Kruka [31]

The element that does not normally form chemical bonds is Xenon.
Reasoning: Xenon is a noble gas and is located in group 18. Noble gases already has a full outer shell of a electron therefore they do not bond, unless with each other.

The focal length of a magnifying glass is the distance between the focal point and optical centre of the magnifying glass.

<h3>Focal length</h3>

The focal length, f is the distance from a lens or mirror to the focal point, F.

This is the distance from a lens or mirror at which parallel light rays will meet for a converging lens or mirror or appear to diverge from for a diverging lens or mirror.

A magnifying glass is a converging lens which produces a enlarged, erect and virtual image when an object is placed between the focal point and optical centre.

A magnifying glass will bring to focus at a point sun rays which can cause the paper to catch fire if it is held in place for long.

This point at which the most concentrated ray of light is shining on the paper, is the focal point for that magnifying glass.

Therefore, the focal length of a magnifying glass is the distance between the focal point and optical centre of the magnifying glass.
