Solution

The correct option is B Passive Remote Sensing
Sensors can be classified on the basis of source of energy. The sensors which depend on external source of energy, usually the sun, are known as Passive sensors, while the sensors which have their own source of energy are known as Active Sensors.

Q. Assertion :The greenhouse effect is a natural process that helps make the Earth warm enough for us to live. Reason: The Earth gets energy from the sun, heats up, and then gives off energy in a different form, called infrared radiation.

Q. All bodies emit heat energy from their surfaces by virtue of their temperature. This heat energy is called radiant energy of thermal radiation. The heat that we receive from the sun is transferred to us by a process which, unlike conduction or convection, does not require the help of a medium in the intervening space which is almost free of particles. Radiant energy travels in space as electromagnetic spectrum. Thermal radiations travel through vacuum with the speed of light. Thermal radiations obey the same laws of reflection and refraction as light does. They exhibit the phenomena of interference, diffraction and polarisation as light does.
The emission of radiation from a hot body is expressed in terms of that emitted from a reference body (called the black body) at the same temperature. A black body absorbs and hence emits radiations of all wavelengths. The total energy

E

emitted by a unit area of a black body per second is given by

E = σ T^{4}

T

is the absolute temperature of the body and

σ

is a constant known as Stefan's constant. If the body is not a perfect black body, then

E = ε σ T^{4}

ε

is the emissivity of the body.
In which region of the electromagnetic spectrum do thermal radiations lie?

Q. The terminology of different parts of the electromagnetic spectrum is given in the text. Use the formula

E = h ν

(for energy of a quantum of radiation: photon) and obtain the photon energy in units of eV for different parts of the electromagnetic spectrum. In what way are the different scales of photon energies that you obtain related to the sources of electromagnetic radiation?

Q. The terminology of different parts of the electromagnetic spectrum is given in the text. Use the formula

E = h v

(for energy of a quantum of radiation photon) and obtain the photon energy in units of

e V

for different parts of the electromagnetic spectrum. In what ways are the different scales of photon energies that you obtain related to the sources of electromagnetic radiation.?

Q. The ratio of energy to frequency of electromagnetic radiation is called:
