Displacement of does not arise due to motion of charge carries but it arises due to time variation of electric flux.

UV light is absorbed by the ozone layer
(i) Source: Sun, arc and ionized gases.
(ii) Uses: To destroy bacteria, sterilizing the surgical instruments, burglar alarm etc

Microwaves are used. They are considered suitable for radar systems for aircraft navigation due to their short wavelength or high frequency. Its wavelength range 1 x 10^-3 m to 3 x 10^-1 m and frequency range is 3 x 10¹¹Hz to 1 x 10⁹ Hz.

Infrared radiation waves are produced by hot bodies and molecules so it is referred as heat waves. (eg. Sun)
(i) Electromagnetic waves having shorter λ than Infrared radiation are visible, U - v, X-rays, and ૪ - rays.
(ii) Electromagnetic waves having longer λ than Infrared radiation are microwaves, radiowaves.

૪ - rays, microwaves, IR, UV rays.
(i) Microwaves < IR < UV < ૪ - rays
(ii) Microwaves < IR > UV > ૪ - rays.

(i) During charging or discharging there is a displacement current, but no conduction current between the plates of the capacitor.
(ii) The displacement current is equal to conduction current I_d = I_c, so I_d = 0.25 A.

(i) Speed of Electromagnetic wave \(=\frac{Peak\ value\ of\ Electric\ field}{Peak\ value\ of\ magnetic\ field}\)
\(c=\frac { { E }_{ 0 } }{ { B }_{ 0 } } \)
(ii) Yes, As Electromagnetic waves contain both electric and magnetic fields, there is a non-zero energy density associated with it.
\(E=\frac { hc }{ \lambda } \)
Momentum p \(=\frac{Total\ energy\ transferred\ to\ the\ surface}{Velocity\ of\ light\ in\ vacuum}\)
i.e.p = \(\frac{U}{c}=mc\)
U - total energy transferred to the surface.
EM waves carry not only energy and momentum but also angular momentum.

It is used in radar systems for aircraft navigation, speed of the vehicle, microwave oven for cooking, and very long-distance wireless communication through satellites.

It is used in radio and television communication systems and also in cellular phones to transmit voice communication in the ultra high frequency band.

When the spectrum obtained from the Sun is examined, it consists of large number of dark lines (line absorption spectrum). These dark lines in the solar spectrum are known as Fraunhofer lines.

The energy crossing per unit area per unit time and perpendicular to the direction of propagation of the electromagnetic wave is called the intensity.
Intensity, I = [u] c or \(I=\frac { total\ electromagnetic\ energy(U) }{ Surface\ area(A)\times time(t) } \)
\(=\frac { Power(P) }{ Surfacearea(A) } \) 

\(\oint _l\vec{B} \cdot \overrightarrow{d l}=\mu_{o} i_{\text {c }}+\mu_{o} \varepsilon_{o} \frac{d}{d t} \oint _s \vec{E} \cdot \overrightarrow{d A}\)

An electromagnetic waves are the waves that are radiated by an accelerated charge which propagates through space as coupled electric and magnetic fields, oscillating perpendicular to each other and to the direction of propagation of the wave.

The displacement current can be defined as the current which comes into play in the region in which the electric field or the electric flux is changing with time.
