Electricity is NOT a part of electromagnetic spectrum.

An electromagnetic spectrum contains electromagnetic radiations arranged according to frequencies and wavelength.

<h2>Further Explanation </h2><h3>Electromagnetic waves </h3>

Electromagnetic waves are types of waves that do not require a material medium for transmission.
These waves are mostly transverse in nature, which means the direction of transmission is perpendicular to the direction of vibration of particles.
They include, light waves, radio waves, x-rays, infra-red, etc.

<h3>Electromagnetic spectrum </h3>

An electromagnetic wave shows electromagnetic waves arranged according to frequencies and wavelength.
Electromagnetic spectrum contains electromagnetic waves: Gamma rays, x-rays, Ultraviolet, Visible light, infra-red, microwaves, and radio waves.
The electromagnetic spectrum is divided into various sections based on wavelength, with gamma rays having the shortest wavelength and radio waves having the longest wavelength.
The part of the electromagnetic spectrum that we can see using our naked eyes is called the visible light spectrum.
In order of frequency, the radio waves have the lowest frequency while gamma rays have the largest frequency.

<h3>General characteristics of electromagnetic waves </h3>

They travel with the speed of light (3.0 x 10^8 m/s)
They possess energy that is given by; E =hf, where h is the plank’s constant and f is the frequency.
They are transverse in nature, and therefore, the wavelength is measured between successful crests or troughs.
They can travel through vacuum

Explanation :

The electromagnetic spectrum shows the wavelength or frequency range of any wave.

It consists of the following waves :

Gamma rays (short wavelength or high frequency)
X-rays
Ultraviolet rays
Visible light
Infrared rays
Microwaves
Radio waves (long wavelength or short frequency)

So, the purple light is not the part of the electromagnetic spectrum.

Hence, the correct option is (c).

When a parachutist jumps from an airplane, he eventually reaches a constant speed, called the terminal speed. Once he has reache

GenaCL600 [577]

Answer:

None of the above forces on air drag on him is equal to his weight

Explanation:

In the velocity-time graph,the gradient of the curve where it is flatten shows the parachutist reaches the terminal velocity when it reaches terminal velocity which means the parachutist reaches constant velocity or speed,indicating that the acceleration of free fall(g) is zero.And according to the resultant force formula weight - air drag= mass*acceleration. so when accelerate is zero,resultant force is zero. And hence the equation will be like this: weight= air drag

a 1000 khz am radio station broadcasts with a power of 20 kw. how many photons does the transmitter antenna emit each second

Gemiola [76]

1000 khz am radio station broadcasts with a power of 20 kw number of photon emitted per second is 30.16 x 10^30 photon/s.

The frequency of the radio station is:

The transmit power is: P = 20kW = 20 X 10^3 W

The transmit power is: h = 6.63 x 10 ^-34 m^2.kg/s

The number of photon emitted per second = N = P/hf = <u>30.16 x 10^30 </u>photon/s.

A cubic sample of a new kind of artificial tissue is subject to an increase in pressure of 160 kPa which results in a reduction

grin007 [14]

Answer:

0.82 MPa

Explanation:

the change in pressure 'σ'=160kPa

K= σ/∈ $Ф_v$ => σ/3∈ $Ф_L$

K= 160/(3 x 0.065)

K=820 kPA=0.82 MPa

Thus,the bulk modulus of the tissue 'K' is 0.82 MPa

State how a ray of light can travel from air into glass without bending?

Katyanochek1 [597]

Answer:

If you shine a beam of light (a bundle of parallel rays) through the air, it will travel in a straight line. Rays of light usually travel in straight lines until they hit something. If a ray of light hits the surface of a sheet of glass, some light will be reflected by the surface of the glass.
